A Tucson family law attorney can no longer practice law. Thomas Tilton was disbarred by the Arizona Supreme Court effective May 1.

The State Bar of Arizona started an investigation in January 2012 after receiving a complaint against Tilton.

In 2006 or 2007, Tilton began using money from his trust account, an account clients' funds are kept in, without keeping records of the account activity, according to court records.

The State Bar was unable to determine the full amount of money used from the account during that time due to a lack of records, court documents state.

But from January 2011 to June 2012, Tilton used at least $105,090.26 from the trust account, document state.

Tilton claims $75,892.31 of that amount was personal money for operating expenses that was misplaced into the trust account, according to court documents.

Tilton contends that he borrowed $29,198.05 from the trust account and agreed to replace it by April 26.

The money was deposited into his trust account and then paid to the Arizona Department of Revenue's Unclaimed Property Unit, said Tilton's attorney, Nancy Greenlee.

Tilton has been an attorney since 1974, according to State Bar records. This is the only disciplinary action taken against him..
