When a person dies, you might have to come to probate court if:

  • the person' property did not pass on automatically according to the title or arrangements such as joint tenancy, community property, or a trust, AND
  • the estate is large enough that the property cannot pass on as a small estate.
Probate court is not generally very difficult. Almost always the case is handled as an informal probate, which means that court orders are signed simply by filing paperwork at court, and without supervision by a judge and any court hearings. Even if part of the case is handled formally, which means a court hearing is necessary to straighten out some detail, the rest of the case can be informal.
