W. Bennett  Cullum

Estate planning, probate, and civil litigation related to these areas of practice are the focus of Bennett Cullum’s practice.

With 45 years of experience, Bennett has prepared hundreds of estate plans, including wills, trusts, family limited partnerships, premarital agreements, marital property agreements, powers of attorney, and other ancillary documents related to estates of various sizes and degrees of complexity.

With regard to probate and trust administration, he has handled the probate of numerous wills and the administration of the estates of decedents and lifetime and testamentary trusts, including matters related to the probate court, the preparation of federal estate and gift tax returns, and the removal and appointment of trustees.

With regard to civil litigation, Bennett now confines his activities primarily to matters arising out of probate and trust administration and real estate transactions.  He has tried cases in federal and state courts primarily in Dallas County and the adjacent counties.
