Burying ashes in two places is legal everywhere in the United States. No federal law prohibits dividing cremated remains, and states treat the decision as belonging to whoever holds the legal right to control disposition. What you do have to work through is the rules at each location you choose, because a portion going into a cemetery, a portion scattered at sea, and a portion buried in a backyard each answer to different authorities.
Who Has the Right to Divide the Ashes
Before any ashes get split, one person has to have the legal authority to make that call. Every state sets a priority order for who decides what happens to a deceased person’s remains. The specifics vary, but the pattern is consistent: a person the deceased formally designated in a written directive or healthcare power of attorney comes first, then a surviving spouse, then adult children (usually a majority if there is more than one), then parents, then siblings, and outward from there.
A written directive from the deceased is the cleanest way to authorize a split. Most states let a competent adult put disposition wishes in writing, and courts routinely honor them. Some states want the document notarized or witnessed; others accept any signed writing. If you want your own ashes divided between two places, putting that in writing and telling your family where the document is kept is the single most effective step. A will can express the same wishes, but a separate disposition directive is usually more practical, because wills are often read after burial decisions have already been made.
When relatives disagree, the statutory hierarchy decides on paper, but courts have generally held that cremated remains are not “property” that can be divided among heirs the way a bank account can. A judge is more likely to award control to one person than to order a split. The reliable fix is a family agreement reached before the cremation.
Rules at Each Burial or Scattering Site
Dividing ashes means satisfying the rules at every location independently. The requirements differ sharply depending on the type of place.
Cemeteries
A cemetery portion is the most straightforward of the options. Most cemeteries offer a columbarium niche, a dedicated cremation plot, or placement alongside an existing full-body burial. Many require an outer container, sometimes called an urn vault, for ground burial. No state law mandates this; cemeteries impose it to keep the ground from sinking as the urn deteriorates. A separate opening-and-closing fee of several hundred dollars is typical on top of the plot or niche cost. Each cemetery sets its own pricing and rules, so if you are splitting between two of them, call both before committing.
Private Property
Scattering on private land is allowed in the large majority of states as long as the landowner agrees. A few states want that permission in writing. Burying ashes on private property is a tighter question. Many states permit it but require you to file a map or legal description of the burial location with the county recorder, and the site may need to be noted on the property deed. Some states require any human burial to take place in an established cemetery or a formally designated family burial ground. Local zoning and HOA rules can add more. Check your local zoning before digging.
Ocean Waters
Scattering ashes at sea is governed by the Marine Protection, Research and Sanctuaries Act. The federal regulation at 40 CFR 229.1 is a general permit that lets anyone scatter cremated remains in ocean waters, with two conditions: the scattering has to happen at least three nautical miles from land, and any flowers, wreaths, or containers placed in the water must be made of materials that decompose readily in the marine environment.1eCFR. 40 CFR 229.1 – Burial at Sea No advance permit application is needed for cremated remains, and there is no water depth requirement.
You do have to report the scattering to the EPA within 30 days. The agency runs an online Burial at Sea Reporting Tool at burialatsea.epa.gov, which accepts submissions as a guest or through a registered account.2US Environmental Protection Agency. Burial at Sea
Rivers, Lakes, and Bays
Inland waters fall outside the MPRSA. Federal law does not regulate scattering ashes in rivers, lakes, or bays; states control it through their own environmental and health agencies.2US Environmental Protection Agency. Burial at Sea Some states allow it freely, some require a permit from the environmental or health agency, and a few prohibit it outright. Call your state’s environmental agency or mortuary board before scattering in any non-ocean waterway.
National Parks and Other Public Lands
Scattering in a national park requires written permission from the park, issued under 36 CFR 2.62(b). Most parks handle this through a letter of permission or a special use permit, usually at no cost.3National Park Service. Scatter Cremated Ashes – Great Smoky Mountains National Park Common conditions include staying at least 100 feet from any water source, avoiding developed areas like trails, roads, and campgrounds, spreading the ashes over a wide area rather than leaving a visible pile, and leaving no markers.4National Park Service. Scattering Cremated Remains Permits Each park sets its own additional restrictions, so contact the superintendent’s office for the one you have in mind. Other federal public lands managed by the Bureau of Land Management or the U.S. Forest Service generally allow scattering without a formal permit, but a call to the local ranger district is sound practice.
Transporting a Portion to the Second Site
Splitting ashes almost always means carrying at least one portion somewhere else. The rules depend on how you are moving them.
The TSA allows cremated remains in both carry-on and checked bags, with one firm requirement: the container must be X-rayable. Wood, plastic, cardboard, and biodegradable fibers pass through screening without trouble. Metal urns, stone, ceramic, and thick glass block the X-ray, and if the screener cannot see inside, the container will not be allowed through the checkpoint. TSA officers will not open a cremation container, even if you ask them to.5Transportation Security Administration. Cremated Remains If you own a decorative metal urn, transfer the ashes to a temporary plastic or wooden container for the flight and repackage them at the destination.
International travel adds paperwork. Most countries require a certified death certificate, a certificate of cremation, and sometimes a letter from the funeral director or a consular authorization. Requirements vary significantly by country. Germany, for example, requires that a licensed cemetery receive the remains and that a licensed funeral director handle the shipment. The U.S. Postal Service will ship cremated remains internationally only via Priority Mail Express International, in its designated cremation remains box, and only to countries that accept the service. Allow at least two weeks for paperwork and consulate coordination.
When Faith Rules Out a Split
Even where the law allows division, a faith tradition may not. The Catholic Church explicitly prohibits dividing cremated remains among family members. A 2023 Vatican instruction reaffirmed that ashes must be preserved whole in a consecrated place suitable for prayer, such as a cemetery or church columbarium. Scattering ashes, keeping them at home, and splitting them among relatives are all forbidden under Catholic teaching. The Church may authorize a family to preserve a “minimal part” of the ashes in a place significant to the deceased, but only under narrow conditions approved by the local bishop.6USCCB. Vatican Offers Further Guidance on Handling Cremains
Orthodox Judaism and Islam generally prohibit cremation itself, so the division question does not arise for observant families. Many Protestant denominations and most Eastern religions have no formal prohibition on dividing ashes, though individual clergy may have preferences. If religious compliance matters to your family, talk to your faith leader before making plans.
Record Each Location
When ashes go to two or more places, documentation matters more than most families expect. Forty years on, a descendant may want to visit one of those sites and have no way to find it. For each portion, record the cemetery name and plot or niche number, or for private land and scattering sites, the street address and GPS coordinates. For a scattering at sea, note the approximate location and the date. Keep copies of any permits, cemetery contracts, EPA notifications, and park permission letters. Store those records with the estate documents, not in a drawer that gets cleaned out after the next move. None of this is legally required for the division itself, but it serves what the burial was meant to serve in the first place: giving people a place to go.
