Yes. It’s common for a house in California to be sold before the probate case officially closes.
A lot of people assume everything has to be finished through the court before the property can even go on the market. That’s not always how it works.
Depending on the executor’s authority and the structure of the probate, the executor may be able to list the property, accept an offer, negotiate terms, and close the sale while probate is still active.
The details matter, though. Authority structure, court involvement, property condition, and family decision-making all affect how the timeline unfolds.
