- Beneficiary disputes: Disagreements among beneficiaries regarding the interpretation of trust terms, the distribution of assets or the trustee’s actions.
- Breach of fiduciary duty: Claims against a trustee for failing to uphold their legal and ethical obligations such as self-dealing, conflicts of interest or mismanagement of trust assets.
