I think that the OP means that the funds are in a lawyer's trust account under a trust condition that they not be disbursed until full and final settlement is reached in the divorce action. The Law Society is a self-governing body for lawyers and
AFAIK does not maintain a trust account.
Probably doesn't change the advice (go to Bank or Credit Union and offer an assignment of your share in the trust $$ as collateral for the loan) but just in the interest of clarity...
