Final answer:
Vested rights of a spouse's retirement plan are considered marital property, while non-vested rights are not.
Step-by-step explanation:
In the context of a spouse's retirement plan, vested rights are considered marital property, while non-vested rights are typically not considered marital property.
Vested rights refer to the portion of a retirement plan that is earned and owned by a spouse, regardless of whether the marriage ends in divorce. These rights are typically divided as part of the marital property during divorce.
Non-vested rights, on the other hand, are rights that have not yet been earned or are contingent upon certain conditions being met. These rights are often not considered marital property because they may not be realized or may be subject to forfeiture in the future.
