Idaho Informal vs Formal Probate

Most Idaho estates never see a judge. A sole-heir surviving spouse might never see probate at all.

Idaho Code § 15-3-711, 15-3-1205

By the FigureMyTax Editorial Team · How we calculate

Quick answer: informal probate, registrar-handled with minimal oversight, is the default for most uncontested Idaho estates. Formal probate requires a judge's hearing and is used for contested or supervised matters. A sole-heir surviving spouse has a third option entirely.

An absolute owner's power, without extra approvals

Worth knowing: under Idaho Code § 15-3-711, a personal representative in informal administration has the same powers over estate property that an absolute owner would have — including selling and deeding real estate — without a separate court order for each transaction. This is part of why informal Idaho probate can move relatively efficiently even when a house needs to be sold.

A third path: the surviving spouse

If the surviving spouse is the estate's sole heir, neither informal nor formal probate is strictly necessary. Under § 15-3-1205, they may petition for summary administration, taking title to the property directly in exchange for personally assuming the estate's debts — a genuinely distinct, faster track available only in this specific situation.

Executor vs administrator is a separate question

Independently of which track applies, Idaho's Uniform Probate Code generally refers to both an executor (named in a will) and an administrator (appointed when there's no will) as the personal representative.

What's the difference between informal and formal probate in Idaho?

Can an Idaho surviving spouse avoid both informal and formal probate?

If they're the estate's sole heir, yes — Idaho Code 15-3-1205 lets a surviving spouse petition for summary administration, taking title directly in exchange for personally assuming the estate's debts, bypassing the standard probate tracks.
