Collateral Relatives
Family members who are related through a common ancestor but not in the direct line of descent (e.g., siblings, aunts, uncles, cousins); relevant in intestate succession and trust distributions.
While straightforward in theory, many businesses fail to actively track obligations tied to this concept - often resulting in missed deadlines, unintended renewals, penalties, or loss of contractual rights.
US Law · For business owners and foundersWhat is a Collateral Relatives?
Collateral relatives are family members who share a common ancestor with you but are not in your direct line of descent. In other words, they are related to you "sideways" through a common ancestor rather than "straight down" (children, grandchildren) or "straight up" (parents, grandparents).
Examples of collateral relatives include siblings, aunts, uncles, cousins, half-siblings, and nieces and nephews. A person's siblings are collateral relatives because they share parents (common ancestors) but neither is descended from the other. Cousins are collateral relatives because they share grandparents but are not directly descended from each other.
Collateral relatives matter primarily in estate planning and intestate succession. If someone dies without a will and has no spouse or direct descendants, their estate typically goes to collateral relatives under state intestacy laws. The order of preference is usually: spouse, children, parents, siblings, then more distant collateral relatives (aunts, uncles, cousins).
In practice, many teams rely on a contract expiry tracking system to stay on top of dates and obligations tied to clauses like this.
Key Elements
Relationship Through Common Ancestor
Collateral relatives are related through a common ancestor (parent, grandparent, great-grandparent, etc.) rather than through a direct line of descent.Distinction from Lineal Relatives
Lineal relatives are in a direct line: ancestors (parents, grandparents) and descendants (children, grandchildren). Collateral relatives are not in this direct line.Intestate Succession Hierarchy
State intestacy laws establish an order of precedence for who inherits if there is no will. Collateral relatives typically inherit only after lineal relatives (spouse, children, parents) are considered.Variable By Jurisdiction
Different states have different intestacy rules. Some states place siblings (collateral relatives) higher in the succession order than others. Some states extend inheritance to distant collateral relatives (cousins); others stop at aunts and uncles.Can Be Expressly Included or Excluded in Wills and Trusts
A testator (person making a will) or grantor (person creating a trust) can expressly include or exclude collateral relatives. Without explicit inclusion, they may inherit only if lineal relatives do not survive.Real-World Example
John Smith dies intestate (without a will) with no spouse or children. His parents are deceased. His estate consists of a house and investments worth $500,000. Under the state's intestacy statute, the order of succession is: spouse, children, parents, siblings, then more distant collateral relatives. John's surviving relatives include: two siblings, an aunt, and a cousin. All are collateral relatives.
Under the typical intestacy statute, John's two siblings (his closest collateral relatives) will inherit the entire $500,000 estate, split equally between them. The aunt and cousin inherit nothing because siblings take precedence. If John had wanted his aunt or cousin to inherit, he would have needed a will or trust that expressly included them.
This is why many businesses adopt automated deadline tracking to ensure no critical dates are missed before they pass.

Trust Distribution to Collateral RelativesWatch Out For
Intestacy Laws Vary Significantly by State
If you do not have a will or trust and die intestate, your estate will be distributed according to your state's intestacy statute. Different states treat collateral relatives differently. If you have preferences about who should inherit, you must have a will or trust.Distant Collateral Relatives May Be Difficult to Locate
If the intestacy statute extends inheritance to distant collateral relatives (like third or fourth cousins), locating all of them can be time-consuming and expensive. Courts may take months to settle an estate because of the need to search for heirs.Collateral Relatives Have No Special Rights to Personal Property
Unless named in a will, trust, or insurance policy, collateral relatives have no legal claim to heirlooms, family photos, or other personal property. These go to the probate estate and are distributed under intestacy law.Blended Families Create Complications
In blended families (where parents remarry), determining who qualifies as a "sibling" or "collateral relative" for inheritance can be complex. Half-siblings may be treated differently depending on the state. Clarify relationships in your will.Don't let collateral relatives deadlines catch you off guard
Key dates tied to collateral relativess - renewal windows, expiry cutoffs, notice periods - can easily slip through the cracks when tracked manually. Missing them triggers automatic extensions, penalties, or lost rights. ExpiryEdge tracks every critical deadline and sends automated reminders before they're due - so nothing slips.
Instead of relying on spreadsheets or manual follow-ups, a centralized renewal reminder system ensures every deadline is visible, tracked, and actioned automatically.
How to Use This in Your Favor
Create a Clear Will or Trust to Control Succession
Do not rely on intestacy laws to distribute your estate as you wish. If you have preferences about which collateral relatives (or anyone else) should inherit, create a will or living trust that expressly names beneficiaries.Name Collateral Relatives as Contingent Beneficiaries in Insurance and Retirement Plans
Life insurance policies and retirement accounts (401k, IRA) pass outside probate to named beneficiaries. If you want collateral relatives to receive these assets, name them as beneficiaries or contingent beneficiaries.Document Your Intention to Exclude Collateral Relatives (If That Is Your Wish)
If you do not want certain collateral relatives to inherit, you can expressly exclude them in your will or trust (sometimes called a "no-contest clause"). This prevents later disputes about whether you simply forgot them.Review Your Estate Plan If Family Circumstances Change
If a collateral relative is born, dies, becomes estranged, or if you have a change of heart, update your will or trust. Family circumstances change; your estate plan should change too.Related Terms
Frequently Asked Questions
Do collateral relatives automatically inherit if there is no will?
Not automatically, but according to the state's intestacy statute. If you die without a will and have no spouse or direct descendants, collateral relatives may inherit in the order specified by your state's intestacy law.
Can you leave money to collateral relatives in a will?
Yes. In a will, you can leave money or property to anyone, including collateral relatives, friends, charities, or pets' trusts (in some states). The will must be valid (properly executed, signed, witnessed).
What happens if a collateral relative is not located after someone dies intestate?
Courts will make reasonable efforts to locate heirs. If a collateral relative cannot be found after a certain period, their share may go to the state (escheated) or distributed to other found heirs depending on the state's law.
Are collateral relatives responsible for debts of the deceased?
No. Collateral relatives (or any heirs) are not personally responsible for the deceased's debts unless they cosigned a loan or guaranteed the debt. However, the estate (property inherited) is used to pay debts before distribution to heirs.
