Multiple-party accounts.

The California Multiple-Party Accounts Law regulates the ownership interest of parties to a multiple-party account, and provides that during the lifetime of the parties, a party's ownership interest is based on the proportion of the party's net contribution to the sums on deposit. This bill instead would base a party's ownership interest in the account on the proportion of the party's net contributions to the account. Existing law provides that rights of survivorship are eliminated for funds withdrawn by a party with a right of withdrawal during the lifetime of the party. This bill instead would eliminate those rights of survivorship with respect to funds withdrawn to the extent of the withdrawing party's net contribution to the account. The bill would also make conforming changes.
