You have five kids. This is not unusual in Utah — the state has the highest birth rate in the country and one of the largest average household sizes. Five kids, a house in Provo, a retirement account, maybe a rental property or two, a truck, and the general sense that you’ll get around to estate planning eventually.
Then you don’t.
Your estate is now being divided into fifths. Your spouse gets a portion, your five children split the rest, and the house — the house that needs someone to actually live in it and maintain it — is now owned by six people who have to unanimously agree on basically everything. Your 19-year-old wants to sell. Your 25-year-old wants to keep it. Your spouse wants to stay in it. The two middle ones don’t care and just want cash. Nobody agrees.
Welcome to Utah intestacy with a large family. The math works fine on a spreadsheet. In practice, it’s a mess.
Here’s the full picture.
Utah’s Intestate Succession Law
Utah follows the Uniform Probate Code, codified in Utah Code Title 75. It’s a modern, relatively clear framework for inheritance. What it can’t account for is your actual family — the dynamics, the relationships, the specific people you’d choose and the ones you wouldn’t.
Married with children (all kids are joint children):
- Your spouse inherits the first $300,000 of your estate, plus 3/4 of the remainder.
- Your children split the remaining 1/4 equally.
Married with children from a prior relationship:
- Your spouse gets the first $225,000 plus 1/2 of the remainder.
- Your children (from all relationships, including prior ones) split the other half.
Married with no children:
- Your spouse inherits everything. Straightforward.
Single with children:
- Your children inherit everything equally, per stirpes (a deceased child’s share goes to their children).
Single, no children, no spouse:
- Your parents inherit equally. If one parent is dead, the survivor takes everything.
- If both parents are dead: siblings and descendants of deceased siblings split it.
- Beyond that: grandparents, then aunts and uncles and their descendants.
The math on a large family:
Under Utah UPC intestacy, with five children who are all joint children of you and your spouse, your spouse gets $300,000 plus 75% of what’s left. Say your estate is worth $800,000 after debts. Your spouse gets $300,000 + 75% of $500,000 ($375,000) = $675,000 total. Your five kids split the remaining $125,000 — $25,000 each.
That’s not catastrophic, but it gets more complex with real property. You can’t divide a house into cash without selling it. Your kids each own a 5% stake in real estate they may not want. And in blended-family scenarios, where some kids are from a prior relationship, the numbers shift further and the family tension increases.
What Probate Looks Like in Utah
Intestate estates in Utah go through district court — Utah’s general trial courts with probate jurisdiction. Utah has adopted the Uniform Probate Code, which means formal and informal probate options exist.
Timeline: 6-12 months for straightforward estates. Informal UPC probate is faster and avoids constant court supervision. Formal probate — required for contested estates or complex assets — takes longer.
Costs: Attorney fees and personal representative fees are “reasonable” by statute, typically running 2-4% of estate value. On a $500,000 estate, budget $10,000-$20,000 in fees before distribution.
UPC options:
- Informal probate: A personal representative is appointed without a formal court hearing and administers the estate under minimal supervision. Efficient for uncomplicated estates.
- Formal probate: Full court-supervised process for complex or disputed estates.
- Small estate affidavit: Utah allows heirs to collect personal property without probate if the entire estate subject to probate is worth $100,000 or less. This is a relatively generous threshold — useful for estates that are primarily liquid assets and personal property, though real estate still requires full probate.
Creditor period: Creditors have 4 months from the date of published notice to file claims. This sets a practical minimum on the probate timeline.
Utah-Specific Quirks
The family size factor:
Utah has the highest fertility rate in the United States. The average number of children per family is higher than the national average, and multigenerational households are common. This matters for intestacy in a specific way: the more children you have, the more fractured your estate becomes under intestate succession. Five children each inheriting 1/4 of what’s left after the spouse takes the UPC share means each child gets a very small fraction of the total. If the estate includes real property, that fractional ownership creates co-ownership complications.
No community property:
Utah is not a community property state. Property is individually titled. Your spouse doesn’t automatically own half of what you earned during marriage — their claim comes through intestacy (or a will), not through marital property law.
No state estate or inheritance tax:
Utah has neither. Your heirs inherit without owing the state anything. Federal estate tax (exemption: $13.6 million in 2026) is unlikely to affect most Utah estates.
Informal UPC probate is genuinely useful:
Unlike traditional probate states, Utah’s UPC-based system allows significant estate administration to happen without constant court involvement. This reduces costs and time for uncomplicated estates. The personal representative has broad authority to act without court orders on most transactions.
Ski property:
Utah has significant vacation property in ski communities — Park City, Deer Valley, Alta, Snowbird. Vacation homes and condominiums are often titled individually, often not discussed in estate planning, and often worth significant amounts. Intestacy treats these like any other asset — divided among all heirs, creating co-ownership that can freeze the property or lead to forced sale.
Religious considerations:
Utah has a large LDS (Mormon) population with strong family and community ties. Estate planning within faith communities often involves charitable giving to the church, bequests to multiple family members, and specific intentions about how assets should be used. None of these intentions are enforceable without a will.
How to Avoid This
Five kids, a house, a retirement account. Under Utah intestacy, everyone gets a portion, nobody got what you actually intended, and the family now co-owns real estate by committee. That’s the no-will outcome.
A will at Killswitch costs $69. You allocate by percentage or by specific asset. You protect your spouse from the math that gives your children co-ownership rights in the family home. You name who you actually trust as executor — not whoever the district court defaults to. You make a ski condo bequest to the kid who actually skis instead of dividing it six ways.
Utah families are large. Utah estates are complicated by that fact. The solution is simple.

Frequently Asked Questions
Q: With five kids, does my spouse end up owning the house alone or do the kids get a share?
A: Under Utah intestacy with five jointly-shared children, your spouse gets the first $300,000 plus 75% of the remainder. If the house is the estate’s main asset, your spouse may end up with majority ownership but your children could have fractional interests — meaning everyone must agree on whether to sell, rent, or stay. A will can give your spouse outright ownership of the house with other assets going to the kids.
Q: Does Utah’s UPC make probate significantly easier than other states?
A: Meaningfully, yes. Utah’s adoption of the Uniform Probate Code allows informal probate that bypasses constant court supervision, reducing both cost and time for uncomplicated estates. The personal representative can handle most transactions without court orders. It’s still 6-12 months and still costs real money — it’s just less brutal than traditional probate states.
Q: What’s Utah’s small estate threshold?
A: $100,000 in probate assets (excluding real estate). Estates below this threshold can use a simple affidavit process to transfer personal property without court proceedings. Real property always requires probate.
Q: What if I have children from two different prior relationships and a current spouse?
A: Utah intestacy gets complicated fast in this situation. Your spouse gets the first $225,000 plus half the remainder. All your children — from every relationship — split the other half equally. Your spouse and your children from prior relationships are now co-heirs. A will lets you structure this cleanly and prevent the obvious conflicts.
Q: Does Utah honor verbal promises about inheritance?
A: No. Verbal statements about who gets what are legally unenforceable in Utah. Courts do not recognize promises made outside a properly executed will. The conversation where you told your eldest they’d get the house means nothing without a document.
