Wyoming follows the "reasonable compensation" standard for trusteesWyo. Stat. Ann. § 4-10-708Verified May 27, 2026. Courts decide what's reasonable on a case-by-case basis, looking at trust size, complexity, and the trustee's actual work. Family-member trustees often waive the fee entirely. Professional trustees (banks, trust companies, attorneys) typically charge between 0.5% and 1.5% of trust assets per year, with corporate fiduciaries usually applying minimum annual fees. The Wyoming trustee compensation calculator breaks it down by trust situation.
Trust administration in Wyoming is typically faster than probate because trusts don't require court supervision. The main floor is the creditor claim period — 4 months in Wyoming — during which the trustee can't safely make final distributions. Simple trusts often wrap up in 6-9 months; trusts that hold business interests, real property in multiple states, or that need to file estate tax returns can take longer. See the Wyoming trustee checklist for the full process.
Estate planning attorneys in Wyoming average $277 per hourClio Legal Trends Report 2025Verified Jan 1, 2025 for wills and estates work. Flat-fee packages run roughly $831–$1,662 for a simple individual will and $3,070–$4,605 for a basic revocable trust. Online and DIY services cost $30–$300 for the same documents — see the will cost calculator for a side-by-side comparison.
Wyoming has a generous small-estate threshold of $400,000. Estates under that line can use the Small Estate Affidavit procedure, which is a form rather than a court case — most families can handle it without an attorney. For estates above the threshold, formal probate generally benefits from counsel because of the procedural overhead, even when nothing is contested. The Wyoming probate calculator estimates total costs based on estate value.
In Wyoming, the situations where retaining counsel is typically worth the cost are: blended families with children from prior relationships; ownership of a business, rental property, or significant investment assets; special-needs dependents who need a special-needs trust to preserve benefits; substantial property held in multiple states. If none of these describe your situation, the simpler online and DIY tools are often enough.
