MBE Rules · Community Property
Commingling and Direct Tracing
Estate of Murphy (1976) 15 Cal.3d 907
The rule
Where separate and community funds are commingled in a single account, the separate-property proponent must trace the specific separate contribution through the account by direct tracing (matching deposits and withdrawals) or by the exhaustion method (showing community funds were spent on family expenses when the separate withdrawal was made).
In plain English
When separate property and community property are mixed in one account, the person claiming the separate property must prove which specific funds were theirs. This can be done by directly matching deposits and withdrawals or by showing that community funds were used for family expenses at the time of the separate withdrawal.
Worked example
Alice has a bank account where she deposits both her salary (community property) and an inheritance (separate property). When she withdraws $5,000 for a family vacation, she must show that this amount came from her inheritance by tracing the specific deposits or demonstrating that community funds were used for other family expenses. If she can successfully trace the funds, she retains her separate property claim.
Memory hook
Trace it or lose it: separate funds must be clearly identified!
The trap
Exams may present scenarios where students assume all funds in a commingled account are community property without considering tracing methods. Students often overlook the need to demonstrate the source of specific withdrawals.
How examiners test it
Questions typically involve fact patterns with mixed accounts and require candidates to analyze the tracing of funds to determine the status of property. Look for prompts that ask about the implications of withdrawals from commingled accounts.
