Defined Contribution Plans in Divorce
Understanding how 401(k), 403(b), TSP, and other defined contribution retirement plans are valued and divided during divorce proceedings, including pre-marriage separate interests.
Understanding Defined Contribution Plans
Defined contribution plans like 401(k), 403(b), and TSP are individual investment accounts. Unlike pensions, balances fluctuate based on investment performance and contribution history.
During divorce, these accounts require careful valuation and division, including proper handling of pre-marriage separate interests through actuarial analysis or agreed values.

Specialized Valuation Expertise Required
Accurate separation of marital and separate-property interests often depends on contribution tracing and growth allocation.
