Estate Planning and Probate

Helping you create a carefully tailored estate plan for your family or business.

Our firm has a long history of preparing wills, modifying wills, trusts, and estate plans to help you create a carefully tailored estate plan for your family or business. The firm can assist you in the coordination of beneficiary designation to ensure the receipt of IRA, retirement, or insurance benefits by the beneficiaries you wish to receive such benefits. The firm also prepares powers of attorney for financial or health care matters which prepare your family or business for future administration of your property and health care decision in time of incapacity.

We understand that the accomplishment of the goals of your estate plan may involve the probate of an estate. To clients this can often be a seemingly unnecessary time consuming and expensive process. However, our firm will do our best to complete the process in a timely manner and in a manner which respects the need to be conservative in the expense associated with a probate. Moreover, we will assist you in bypassing probate if at all possible.

The Duncan Law Firm, LLP, will assist with the transfer of assets to your beneficiaries or heirs and the protection of your assets. If a probate is necessary, the appointment of a personal representative will be promptly handled as will providing notice to creditors, and representing the personal representative in all court proceedings. The firm will be available at every step of the process to assist the personal representative in the fulfillment of their duties and responsibilities.
