Estate is over 100.000 what form do i file with the court

Unfortunately you will have to file a petition for probate (intestacy if no Will). The insurance company will request "Letters of Administration" and to get them you have to file a petition for probate. You might be able to do this on your own or through a local attorney. The fee for that service will be a percentage of the total estate- 4% of the first $100,000 and 3% of the next $100,000 plus costs of filing (probably around $1200 now that the courts are raising their fees). This comment does not constitute the giving of legal advice nor create an attorney client relationship.

Donald is correct. Unfortuantely, once the estate gets over $100,000, the financial institutions will want to see Letters from the court. If I can be of assistance, please feel free to contact me at 530-344-0204.

Based on the limited information in your question there doesn't appear to be any way to avoid a petition for probate (DE-111). The rules for filing and noticing the probate petition hearing are complex; you will want to consult with a probate attorney in your area to discuss these and to discuss whether any probate-avoiding device can be used.
