  • Revocable living trusts that govern the ease of lifetime property management
  • Durable powers of attorney authorizing trusted ones to act when one cannot

Needham and Associates regularly provide Oklahoma probate law advice and probate court representation. Probate can include representing individuals and families in settling a family member’s estate, including the court procedures necessary to determine the content and nature of an estate, complete the payment of debts, expenses, and taxes of the estate, and obtaining court authorization for distribution of the estate to heirs and beneficiaries. We represent the estates of clients in the probate of a last will and testament and the estates where there is no will under intestate succession laws of Oklahoma. Representation of clients by Needham & Associates in these contexts includes advisement on distribution of real property assets, equity accounts, employee benefits, retirement accounts, and life insurance policies. Our attorneys will also resolve disputes of estate taxation with authorities.

Our attorneys are experienced in trust administration issues that must be considered or resolved in a court proceeding. These situations can include questions related to interpretation of trust instruments, the securing of court approval of an amendment of a trust, and disputes over the terms of a trust or its administration by a trustee.

Needham & Associates provides compassionate counsel in all matters relating to legal guardianship. Clients in guardianship matters require representation before the court administration and oversight of managing financial needs and care for children and the incapacitated.
