Nick Reiner, who is accused of killing his parents, filmmaker Rob Reiner and producer Michelle Singer Reiner, is asking a California court to release money from a trust fund they established for him so he can pay legal expenses and cover basic necessities while jailed awaiting trial.

In a probate petition filed Monday and obtained by People magazine, Reiner, 32, seeks access to more than $1.5 million held in a trust created by his parents. Reiner argues he should have received half of the trust when he turned 30 and that the trustee has improperly withheld funds.
