Protecting Your Rights in Trust and Probate Disputes
Contact Us

The loss of a loved one is hard enough—but when disputes arise over the transfer of wealth, you need experienced legal counsel that delivers results. Our Seattle-based trust and estate litigation attorneys use creative and effective strategies, including Washington’s Trust and Estate Dispute Resolution Act (TEDRA), to resolve even the most complex probate and inheritance conflicts.

We offer a full range of dispute resolution services, from informal negotiation and mediation to aggressive representation in court, to protect your rights and achieve favorable outcomes.

Skilled Counsel for Complex Trust and Estate Disputes

Trust and estate disputes are emotionally charged and legally complex. They require attorneys who understand sensitive family dynamics and who are well-versed in the full range of legal tools available for resolving these matters.

Our Trust & Estates Litigation practitioners have successfully represented a wide variety of parties, including:

  • Adult and minor beneficiaries

  • Court-appointed guardians and special representatives

  • Corporate fiduciaries and financial institutions

  • Trust entities and estates

Representative Matters

Here are a few recent examples of our team’s work:

  • Served as court-appointed guardian ad litem for three minor beneficiaries in a contested trust distribution, successfully resolved through mediation.

  • Represented a trust beneficiary in securing court appointment of their preferred trustee.

  • Advocated for a surviving spouse whose in-laws contested a trust established for her late husband; the dispute was resolved through a favorable settlement.

  • Represented personal representatives and spouses in disputes over the enforceability of prenuptial agreements, using extensive motion practice and discovery to reach successful outcomes.

Two estate attorneys at Lasher Holzapfel Sperry & Ebberson who started a complex estate settlement almost 10 years ago, retired after 6 years, but remained to complete the settlement which concluded 9 years and 7 months later. They remained committed through three separate court appeals trials and prevailed. All remaining procedures to finish the estate closure satisfactorily have been completed. This is quality service above and beyond what was expected. All legatees were pleased and honors go to Trini Brothers the legal secretary for her promptness in answering well over a thousand emails over the 9 year period.
