Letters of administration in Prosper, TX
Prosper is about 13 miles from the Collin County courthouse in McKinney, and Collin County's probate court says many uncontested cases are heard by Zoom, so the drive may never come up.

Reference cost
$2,000-$6,000 all-in for this path, including the filing fee, certified copies, and notary work. Attorney fees push administration higher.
Two counties
Prosper spans Collin and Denton counties. The county where the person lived decides the court.
Which county handles a Prosper estate
Texas files probate in the county where the person lived, not where they died or where the bank is. Texas Estates Code § 33.001 sets that rule. Prosper lies in both Collin and Denton counties, with the western part of town in Denton County.
To check, look at the person's property tax statement or voter registration certificate, which name the county, or search the address on the Collin County appraisal district and Denton County appraisal district sites.

The heirship step in a no-will estate
With no will, the court has to confirm who inherits before it appoints anyone. Texas Estates Code § 401.003 bars an independent administrator in a no-will estate until a heirship proceeding establishes that the applicants are all of the heirs. Two disinterested witnesses who know the family history testify at that hearing.
The court also appoints an attorney ad litem, a lawyer who represents any heirs whose names or locations are unknown, as Section 202.009 requires. The court sets that fee, and the estate pays it. Denton County's probate court lists a $600 ad litem deposit as of February 2025. Ask the Collin County probate clerk for its current deposit.

Why does a no-will estate need an heirship hearing?

The court also appoints an attorney ad litem to represent any unknown heirs, and the estate pays that fee. Two witnesses who know the family history testify at the hearing.
Who can get letters of administration when there is no will?
Texas Estates Code Section 304.001 sets the order. With no will, the surviving spouse comes first, then the next of kin, then a creditor, then other qualified people the statute lists. The court makes the appointment after the hearing.
How do I know if a Prosper home is in Collin or Denton County?
The person's property tax statement and voter registration certificate both name the county. You can also search the address on the Collin and Denton central appraisal district websites. The county where the person lived decides where the case is filed.
Do I have to go to the courthouse in McKinney for the hearing?
Not always. Collin County's probate court says uncontested probate cases are often handled by Zoom, and its website posts the Zoom hearing instructions. The court decides the format, so follow the instructions in your hearing notice.
How long does it take to get letters of administration in Prosper?
Courts usually set an uncontested hearing two to four weeks after filing, after a 10-day citation period. The clerk issues letters once the administrator takes the oath and meets any bond requirement. No-will cases can take longer because the heirship proceeding and the attorney ad litem's work come first.
