Nick Reiner claims siblings withdrew support for legal defense in new filing

Nick Reiner has accused his siblings of backing out of an agreement to help fund his legal defense, according to newly filed court documents related to his ongoing criminal case.

The 32-year-old, who has pleaded not guilty to charges connected to the deaths of his parents, filmmaker Rob Reiner and producer Michele Singer Reiner, recently filed a probate petition seeking access to a $1.5 million trust established in his name.

According to the filing, Reiner is requesting access to the funds in part to rehire attorney Alan Jackson, who initially represented him following his arrest before later withdrawing from the case.

Court documents allege that Jackson agreed to take on the representation based on assurances that Reiner's siblings, Jake Reiner and Romy Reiner, would act as third-party payors and help cover the costs of his legal defense.

In a declaration submitted in support of the petition, Jackson stated that he proceeded with the representation after receiving verbal commitments regarding funding arrangements.

“Mr. Reiner's siblings participated in communications concerning the representation and agreed verbally to act as third-party payors for Mr. Reiner's defense,” Jackson wrote.

He further claimed that family representatives assured him the agreed-upon funding would be provided promptly, a factor he said influenced his decision to accept the case.

However, Jackson alleged that in late December 2025 he was informed by a family representative that the anticipated third-party funding would not be provided.

“That position was inconsistent with the prior assurances on which my firm had relied,” Jackson stated in the declaration.

According to the filing, the absence of funding ultimately made continued private representation financially unfeasible, prompting the attorney to seek withdrawal through the appropriate court procedures.

Reiner is currently represented in the criminal case by public defender Kimberly Greene.

The probate petition also includes correspondence from attorney Anita P. Wu, who wrote on Reiner's behalf that Jackson's legal fees had allegedly been negotiated and approved by his siblings before that commitment was later reversed.

Despite his previous withdrawal, Jackson stated in his declaration that he remains willing to represent Reiner and would consider alternative arrangements regarding payment.

The filing does not specify whether the original funding was expected to come from Reiner's trust, other family trusts or another source altogether.

It also does not identify Reiner's siblings as trustees of the trust fund, meaning it remains unclear what authority, if any, they had over the proposed distribution of funds.

The allegations outlined in the probate petition have not been independently verified in court, and no public response from Jake Reiner or Romy Reiner was included in the filing.

The criminal case against Reiner remains pending.
