A Plan That Changes With You

An estate plan should reflect your life today while preparing for what may come next. Marriage, children, retirement, changes in assets, the sale or growth of a business, and other major life events may affect an existing plan.


White Peterson helps clients create, review, and update estate plans so their documents continue to reflect their wishes, responsibilities, and goals.

  • FAQs

Estate Planning FAQs

  • Do I need a will or a trust?

    The right approach depends on your assets, family circumstances, goals, and how you want your estate to be managed and distributed. An attorney can help determine which estate planning tools are appropriate for your situation.

  • When should I update my estate plan?

    It is a good idea to review your estate plan after significant life or financial changes, such as marriage, divorce, the birth of a child, retirement, acquiring significant assets, or changes involving a family business or farm.

  • What is the difference between probate and trust administration?

    Probate is the court-supervised process used to administer certain estates after death, while trust administration involves managing and distributing assets held in a trust. The process that applies depends on how the estate was structured and the assets involved.
