Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Portfolio, a series of Lazard Retirement Series, Inc. (the “Fund”), but does not reflect the fees or charges imposed by the separate accounts of certain insurance companies (the “Participating Insurance Companies”) under variable annuity contracts or variable life insurance policies (the “Policies” and each, a “Policy”). If such fees and charges were reflected, the figures in the table would be higher.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Portfolio’s performance. Because the Portfolio had not commenced investment operations prior to the date of this Prospectus, no portfolio turnover information is presented.

Expense Example [Heading] rr_ExpenseExampleHeading Example
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then hold or redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same, giving effect to the expense limitation agreement in year one only. The Example does not reflect fees and expenses imposed by the Participating Insurance Companies under the Policies; if they were reflected, the figures in the Example would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Portfolio invests primarily in equity securities, principally common stocks, of US and non-US companies. In managing the Portfolio, the Investment Manager utilizes a quantitatively driven, bottom up stock selection process. A principal component of the Investment Manager’s investment process for the Portfolio is volatility management. Volatility, a risk measurement, measures the magnitude of fluctuations in the value of a financial instrument or index over time. The Investment Manager seeks to generate attractive risk-adjusted equity returns (returns after accounting for the risk taken to achieve those returns) while lowering portfolio volatility (up and down movements in the fund’s returns). The Investment Manager’s investment process is benchmark-unaware, which means that the Portfolio’s assets are not managed by reference to a benchmark index. The Investment Manager examines fundamental company information (such as financial statements) and seeks to identify high quality companies with sustainable operating performance in order to build a well-diversified global portfolio of common stocks. The Investment Manager performs an independent assessment of stock risk and also seeks to manage risk through diversification.

The Portfolio management team selects investments for the Portfolio from a broad investment universe of stocks and depositary receipts, including American Depositary Receipts (“ADRs”), Global Depositary Receipts and European Depositary Receipts, real estate investment trusts (“REITs”), warrants and rights. The active, quantitative approach utilized by the Portfolio management team involves initial screening, risk assessment and evaluation of each company relative to its global peers. The Portfolio will typically focus on securities of developed market companies, using an objective, systematic investment process that blends both risk and stock ranking assessments designed to capture attractive risk-to-return characteristics and create a low volatility portfolio. In addition to a multidimensional assessment of risk, each company is evaluated daily according to four independent measures: growth, value, sentiment and quality. The Portfolio may invest across the capitalization spectrum.

Under normal circumstances, the Portfolio invests at least 80% of its assets in equity securities.

The Portfolio may invest in exchange-traded open-end management investment companies (“ETFs”), generally those that pursue a passive index-based strategy.

Because the Portfolio had not commenced investment operations prior to the date of this Prospectus, no performance returns are presented. Annual performance returns provide some indication of the risks of investing in the Portfolio by showing changes in performance from year to year. Comparison of Portfolio performance to an appropriate index indicates how the Portfolio’s average annual returns compare with those of a broad measure of market performance. After the Portfolio commences investment operations, performance information will be

available at www.lazardassetmanagement.com or by calling (800) 823-6300. The Portfolio’s past performance is not necessarily an indication of how the Portfolio will perform in the future.

Lazard Retirement Managed Equity Volatility Portfolio | Market Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Market Risk: The Portfolio may incur losses due to declines in one or more markets in which it invests. These declines may be the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s). To the extent that such developments impact specific industries, market sectors, countries or geographic regions, the Portfolio’s investments in such industries, market sectors, countries and/or geographic regions can be expected to be particularly affected, especially if such investments are a significant portion of its investment portfolio. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Portfolio. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war or military conflict, acts of terrorism, the spread of infectious illness or other public health issues, social unrest, supply chain disruptions, government defaults, government shutdowns, the imposition of sanctions and other similar measures, recessions or other events could have a significant negative impact on global economic and market conditions. For example, a public health or other emergency and aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, may have severe negative impacts on markets worldwide. Additionally, general market conditions may affect the value of a Portfolio’s securities, including changes in interest rates, currency rates or monetary policies.

Lazard Retirement Managed Equity Volatility Portfolio | Issuer Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Issuer Risk: The value of a security may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets or factors unrelated to the issuer’s value, such as investor perception.

Lazard Retirement Managed Equity Volatility Portfolio | Non-US Securities Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Non-US Securities Risk: The Portfolio’s performance will be influenced by political, social and economic factors affecting the non-US countries and companies in which the Portfolio invests. Non-US securities carry special risks, such as less developed or less efficient trading markets, political instability, a lack of company information, differing auditing and legal standards, and, potentially, less liquidity. Non-US securities may be subject to economic sanctions or other similar governmental actions or developments, which could, among other things, effectively restrict or eliminate the Portfolio’s ability to purchase or sell certain foreign securities. To the extent the Portfolio holds securities subject to such actions, the securities may become difficult to value and/or less liquid (or illiquid). In some cases, the securities may become worthless.

Lazard Retirement Managed Equity Volatility Portfolio | Foreign Currency Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Foreign Currency Risk: Investments denominated in currencies other than US dollars may experience a decline in value, in US dollar terms, due solely to fluctuations in currency exchange rates. The Portfolio’s investments denominated in such currencies, as well as any investments in currencies themselves, could be adversely affected by delays in, or a refusal to grant, repatriation of funds or conversion of currencies. Irrespective of any foreign currency exposure hedging, the Portfolio may experience a decline in the value of its portfolio securities, in US dollar terms, due solely to fluctuations in currency exchange rates. The Investment Manager does not intend to actively hedge the Portfolio’s foreign currency exposure.

Lazard Retirement Managed Equity Volatility Portfolio | Depositary Receipts Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Depositary Receipts Risk: ADRs and similar depositary receipts typically will be subject to certain of the risks associated with direct investments in the securities of non-US companies, because their values depend on the performance of the underlying non-US securities. However, currency fluctuations will impact investments in depositary receipts differently than direct investments in non-US dollar-denominated non-US securities, because a depositary receipt will not appreciate in value solely as a result of appreciation in the currency in which the underlying non-US dollar security is denominated.

Lazard Retirement Managed Equity Volatility Portfolio | Quantitative Model Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Quantitative Model Risk: The success of the Portfolio’s investment strategy depends largely upon the effectiveness of the Investment Manager’s quantitative model. A quantitative model, such as the risk and other models used by the Investment Manager requires adherence to a systematic, disciplined process. The Investment Manager’s ability to monitor and, if necessary, adjust its quantitative model could be adversely affected by various factors including incorrect or outdated market and other data inputs. Factors that affect a security’s value can change over time, and these changes may not be reflected in the quantitative model. In addition, factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value.

Lazard Retirement Managed Equity Volatility Portfolio | Volatility Management Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Volatility Management Risk: While the Investment Manager generally will seek to achieve, over a full market cycle, the level of volatility in the Portfolio’s performance as described above, there can be no guarantee that this will be achieved; actual or realized volatility for any particular period may be materially higher or lower depending on market conditions. In addition, the Investment Manager’s efforts to manage the Portfolio’s volatility can be expected, in a period of generally positive equity market returns, to reduce the Portfolio’s performance below what could be achieved without seeking to manage volatility and, thus, the Portfolio would generally be expected to underperform market indices that do not seek to achieve a specified level of volatility.

Lazard Retirement Managed Equity Volatility Portfolio | Small and Mid Cap Companies Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Small and Mid Cap Companies Risk: Small and mid cap companies carry additional risks because their earnings tend to be less predictable, their share prices more volatile and their securities less liquid than larger, more established companies. The shares of small and mid cap companies tend to trade less frequently than those of larger companies, which can have an adverse effect on the pricing of these securities and on the ability to sell these securities when the Investment Manager deems it appropriate.

Lazard Retirement Managed Equity Volatility Portfolio | Large Cap Companies Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Large Cap Companies Risk: Investments in large cap companies may underperform other segments of the market when such other segments are in favor or because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain high growth rates during periods of economic expansion.

Lazard Retirement Managed Equity Volatility Portfolio | REIT Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

REIT Risk: REITs are subject to similar risks as an investment in a realty-related company. Consequently, investments in REITs could lead to investment results that may be significantly different from investments in the broader securities markets. The risks related to investments in realty-related companies include, but are not limited to: adverse changes in general economic and local market conditions; adverse developments in employment; changes in supply or demand for similar or competing properties; unfavorable changes in applicable taxes, governmental regulations and interest rates; operating or development expenses; and lack of available financing. Due to certain special considerations that apply to REITs, investments in REITs may carry additional risks not necessarily present in investments in other securities. REIT securities (including those trading on national exchanges) typically have trading volumes that are less than those of securities of other types of companies, which may affect the Portfolio’s ability to trade or liquidate those securities. An investment in a REIT may be adversely affected if the REIT fails to comply with applicable laws and regulations, including failing to quality as a REIT under the Internal Revenue Code of 1986, as amended. Failure to qualify with any of these requirements could jeopardize a company’s status as a REIT. The Portfolio generally will have no control over the operations and policies of a REIT, including qualification as a REIT.

Lazard Retirement Managed Equity Volatility Portfolio | ETF Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

ETF Risk: Shares of ETFs may trade at prices that vary from their net asset values, sometimes significantly. The shares of ETFs may trade at prices at, below or above their net asset value. In addition, the performance of an ETF pursuing a passive index-based strategy may diverge from the performance of the index. The Portfolio’s investments in ETFs are subject to the risks of the ETFs’ investments, as well as to the general risks of investing in ETFs. The Portfolio will bear not only the Portfolio’s management fees and operating expenses, but also the Portfolio’s proportional share of the management fees and operating expenses of the ETFs in which the Portfolio invests. Although Section 12 of the Investment Company Act of 1940, as amended (the “1940 Act”) limits the amount of the Portfolio’s assets that may be invested in one or more ETFs, Rule 12d1-4 under the 1940 Act allows the Portfolio to acquire the securities of another investment company, including ETFs, in excess of the limitations imposed by Section 12 of the 1940 Act, subject to certain limitations and conditions.

Lazard Retirement Managed Equity Volatility Portfolio | Other Equity Securities Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Other Equity Securities Risk: Investments in rights and warrants involve certain risks, including the possible lack of a liquid market for resale, price fluctuations and the failure of the price of the underlying security to reach a level at which the right or warrant can be prudently exercised, in which case the right or warrant may expire without being exercised and result in a loss of the Portfolio’s entire investment.

Lazard Retirement Managed Equity Volatility Portfolio | Securities Selection Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Securities Selection Risk: Securities and other investments selected by the Investment Manager for the Portfolio may not perform to expectations. This could result in the Portfolio’s underperformance compared to other funds with similar investment objectives or strategies.

Lazard Retirement Managed Equity Volatility Portfolio | High Portfolio Turnover Risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

High Portfolio Turnover Risk: The Portfolio’s investment strategy may involve high portfolio turnover (such as 100% or more). A portfolio turnover rate of 100%, for example, is equivalent to the Portfolio buying and selling all of its securities once during the course of the year. A high portfolio turnover rate could result in high transaction costs.
