Patricia and Robert are married and hold their Bellevue home as community property with right of survivorship. Patricia owned a separate brokerage account worth $200,000 before the marriage. During the marriage, she deposits her paycheck into the same brokerage account without keeping separate records. Robert later claims that the entire brokerage account is community property. Under Washington's community property laws, what legal doctrine is most relevant to this dispute?

Correct Answer

A) The doctrine of commingling, which may cause separate property to lose its separate character when mixed with community funds without adequate tracing

The doctrine of commingling is directly applicable here. Under Washington community property law, when separate property funds are mixed (commingled) with community property funds in the same account without adequate records to trace which funds are separate, the separate property may lose its separate character and become community property. Patricia's failure to keep separate records of her pre-marital funds mixed with marital earnings (paychecks) creates a commingling problem that could cause the entire account to be treated as community property. Proper tracing is the key to preserving separate property status.
