Dividing pension benefits in a Michigan divorce

Dividing pension benefits in a Michigan divorce:  A pension plan is a contract for the payment of a fixed sum of usually following retirement.  The plans are also known as defined benefit plans because the fixed sum of money is a “defined benefit”.


In a Michigan divorce, property acquired during the course of the marriage is typically divided and property acquired before you were married is not.  Michigan divorce law provides that a pension benefit is property, just like a bank account and can be divided in a divorce, provided it was earned during the marriage.  Any portion of a pension earned during the marriage is called the marital portion.

Sometimes, calculating the marital portion can be difficult.  With a bank account, your Michigan divorce lawyer will request you obtain a bank balance close to the date of marriage and a current balance.  The marital portion is the difference between the two.

With a pension benefit you cannot obtain a balance close to the date of marriage.  Rather, a pension benefit changes with the number of years of credited service.  So how do you calculate the marital portion of a pension benefit?

A good way to estimate the marital portion is to divide the number of years of marriage by the number of years of employment.

For example take the following into account:

Pat’s current pension value:  $1000.00 per month.

Pat has been employed for 10 years and married to spouse for 5 years.

The marital portion would be (5 years of marriage /10 years of employment) or 50%.  Therefore, spouse would be entitled to 1/2 of the marital portion of the pension benefit, 25% or $250.00 per month.

This formula is called the coverture fraction and is the most popular formula utilized however, it is not the only way to determine the marital portion of a pension plan under Michigan divorce law.

In fact, there are three different methodologies under Michigan divorce law to solve the problem and they are not equal.  See:   https://www.thedivorceguy.com/dividing-pension-benefits-not-all-language-is-created-equa/

Just because you have been awarded 50% of the marital portion may not be good enough. The methodology should be included in the Judgment Divorce to ensure that the division is fair.
