If you die without a valid will in Montana, state law — not your personal wishes — decides who inherits your property. This is called intestate succession, and it follows a fixed legal formula based on your surviving relatives, regardless of your actual relationships, promises you may have made, or what you would have wanted. For many families, the results are different from what the deceased would have chosen, and often more complicated to sort out.
How Montana’s Intestate Succession Works
- Married with no children, or only children shared with your spouse: your spouse generally inherits everything
- Married with children from outside the marriage: your spouse and those children split the estate according to a specific formula
- Unmarried with children: your children inherit, divided equally
- No spouse or children: assets pass to parents, then siblings, then more distant relatives, following a specific legal order
Who Intestate Succession Leaves Out
- Unmarried partners, regardless of relationship length, have no automatic inheritance rights under Montana intestate law
- Stepchildren you never formally adopted are not included unless specifically provided for
- Close friends, chosen family, or charities you would have wanted to support receive nothing
- Specific personal items you’d want to go to specific people are instead divided according to the same formula as everything else
Intestate Succession Doesn’t Just Redirect Assets — It Adds Complexity
Without a will naming a personal representative, the court appoints one, who may not be who you would have chosen. Without a will naming a guardian, the court decides who raises your minor children — a decision made by a judge with limited insight into your actual wishes. The probate process for an intestate estate often takes longer and involves more court involvement than an estate with a clear will.
Common Misconceptions
- “My spouse will automatically get everything” — not always true if you have children from a previous relationship
- “My family will just sort it out” — Montana law doesn’t leave room for informal family agreements to override the legal formula without a court process
- “I don’t have enough to worry about this” — intestate succession applies regardless of estate size, and smaller estates without a will can still involve the same court process, just for less at stake
The Simple Fix
A basic will resolves nearly all of this: it lets you name your own personal representative, name a guardian for minor children, and direct your assets to the people, or causes, you actually choose. For most Montanans, having any valid will is a significant improvement over relying on the state’s default formula.
Don’t Leave These Decisions to a Formula
A will is one of the most straightforward ways to make sure your wishes — not a state formula — determine what happens to your property and your family. Columbia Falls Estate Planning can help you put one in place.
Frequently Asked Questions
What happens to my property if I die without a will in Montana?
Your property is distributed according to Montana’s intestate succession laws, which follow a fixed formula based on your surviving relatives rather than your personal wishes.
Does my spouse automatically inherit everything if I die without a will?
Not always. If you have children from outside your current marriage, your spouse and those children typically split the estate according to a specific legal formula, rather than your spouse inheriting everything.
Can an unmarried partner inherit under Montana intestate law?
No. Unmarried partners have no automatic inheritance rights under Montana’s intestate succession laws, regardless of how long the relationship lasted.
Who decides who raises my children if I die without a will?
A court decides, typically with more limited insight into your actual wishes than you would have provided in a will naming a guardian yourself.
Is intestate succession different for a small estate?
The same distribution formula applies regardless of estate size, though Montana’s small estate affidavit process may simplify the administrative steps for smaller estates.

I stumbled upon PictureMT a few months ago while searching for a guide on using manual mode, and I can honestly say it changed the way I see photography. As someone who always admired great photos but never had formal training, I felt overwhelmed by technical jargon and endless gear options. Most tutorials I found elsewhere were either too advanced or too basic. But PictureMT found that perfect balance. Their content speaks to photographers like me — passionate, curious, and eager to grow.
From the first blog I read, I felt like I was learning from a friend rather than a textbook. The tutorials are straightforward, the examples are real, and the tone is incredibly motivating. I especially love their editing guides — they helped me transition from using basic phone filters to confidently editing in Lightroom and Snapseed.
