Estate Planning and Probate

50 Years of Experience Helping Clients Plan for the Future

Estate planning is used to organize your assets and determine how they will be distributed after your death. You have worked hard your whole life to build a strong inheritance and take care of your loved ones, and estate planning is the best way to ensure that protect continues after you are no longer around to do it yourself.

At Leach & Sullivan, we have over 50 years of experience preparing the necessary estate planning documents for clients throughout Duncan and Stephens County, Oklahoma. Contact our firm online or call 580-255-1111 to schedule your appointment.

Estate Planning

Unlike some firms that do not have the capacity to handle large estates or those that will not meddle with small affairs, our lawyers handle work with clients to handle every step of the estate planning process, from the simplest to most complex estates. Our attorneys:

  • Draft wills
  • Set up trusts
  • Minimize potential estate tax liability
  • Establish revocable trusts
  • Work with families who need special needs trusts for children with developmental disabilities
  • Assist with Medicare planning through assets distribution
  • Draft powers of attorney
  • Prepare advanced healthcare directives

Estate Administration and Probate

Estate administration and probate is the process of distributing an individual's assets after their death. Assets are distributed according to a person's will or according to Oklahoma law if there is not a will. The probate process is often time consuming and complex, but it can be made simpler with the assistance of an experienced, capable probate attorney.

In some cases, disputes arise in the process of trust administration or estate administration. Our litigation attorneys handle all types of trust, estate and probate litigation.

Contact Knowledgeable and Experienced Lawyers

In addition to over 50 years of experience, we also bring a wealth of knowledge to our clients. One of our attorneys has an LLM in tax, so we can focus in tax planning during the estate planning process.
