Phoenix, AZ estate planning attorney Mark A. Bregman talks specifically how much one can expect probate to cost. He explains that in Arizona, a straightforward probate without significant administrative complications typically costs between $4,000 and $5,000. In some cases, the expense may be slightly lower, though it is often higher when disputes arise. Increased costs generally stem from conflicts involving creditors, disagreements between beneficiaries and executors, or other contested matters within the estate.
