Miami County, Ohio · Troy

A relative or other non-parent — often a grandparent — can ask the Juvenile Court for legal custody of a child when living with a parent is not in the child's best interest. This is different from adoption (which permanently ends parental rights) and from guardianship (a Probate matter).

How can a grandparent or non-parent get custody in Miami County, Ohio?

File a complaint for legal custody as a non-parent in the Miami County Juvenile Court under R.C. 2151.23 / 2151.353; the court weighs the child's best interest and whether a parent is unsuitable. For short-term needs, the Juvenile Court accepts a Grandparent Power of Attorney and a Caretaker Authorization Affidavit (both limited to grandparents) so a caregiving grandparent can make school and medical decisions; these forms are in the county Forms Center. The custody filing fee is $135.00 per child. Legal custody does not end the parents' legal status or support duty.

Gavvl Law for grandparent and non-parent custody in Miami County

When living with a parent is not in a child's best interest, a grandparent or other relative can ask the Miami County Juvenile Court for legal custody under R.C. 2151.23 and 2151.353. It is not adoption and it does not end the parents' support duty — but it gives a caregiver real authority over school and medical decisions. Gavvl Law files the custody complaint and, when you need to act now, the grandparent short-term forms, on a flat fee with payment plans.

Short-term authority while the case is pending. For immediate school and medical decisions, the Juvenile Court accepts a Grandparent Power of Attorney and a Caretaker Authorization Affidavit — both limited to grandparents — from the county Forms Center. We put those in place right away so you can act for the child while the legal-custody case works through the court.
Meeting the parental-unsuitability standard. A non-parent custody case turns on the child's best interest and whether a parent is unsuitable, filed at $135 per child in the Juvenile Court. We build the evidence that meets that standard, because a relative does not win custody simply by being the better caregiver — the court must first find the parent unfit or unsuitable.
Legal custody explained, at a flat fee. Legal custody under R.C. 2151.23 / 2151.353 does not permanently end parental rights or the support duty the way adoption does, and it is separate from Probate guardianship. We explain which tool fits your family and handle the Juvenile Court filing on a flat fee, with financing available for a contested case.

Grandparent and non-parent custody is always decided in the Miami County Juvenile Court at (937) 440-5970, which may appoint a Guardian ad Litem to investigate. We prepare your complaint, the UCCJEA parenting affidavit, and your evidence of the child's circumstances so the court — and any GAL — sees why your home is the child's best option.

Flat-fee options

Flat-fee limited scope: we draft and file the grandparent companionship/visitation motion or a non-parent custody complaint. You appear at any hearing.

Grandparent companionship / visitation motion: $950
Non-parent custody complaint: $1,250

Prefer full representation? An Ohio attorney can carry the entire case on a $3,500 retainer.

Split any flat fee with Gavvl Direct — our in-house plan at 19% APR, $500 minimum — on a 60%-down schedule of 18 weekly, 8 bi-weekly, or 4 monthly payments, or full financing where work begins once 60% is paid. Affirm, Klarna, and PayPal Pay Later are also available through LawPay.

Miami County Practice Notes

Legal custody is not adoption. Non-parent legal custody under R.C. 2151.23 / 2151.353 does not permanently end the parents' rights or their support duty. Adoption (a Probate matter) permanently transfers parentage; guardianship is a separate Probate process.

Frequently Asked Questions

I'm a grandparent caring for my grandchild in Miami County — what can I file?: For short-term needs, the Juvenile Court accepts a Grandparent Power of Attorney and a Caretaker Authorization Affidavit (both limited to grandparents) so you can make school and medical decisions; these forms are in the county Forms Center. For a longer-term order, you can file a complaint for legal custody as a non-parent in the Juvenile Court under R.C. 2151.23 / 2151.353. Legal custody is different from adoption — it does not end the parents' legal status or support duty.
Is non-parent legal custody the same as adoption in Miami County?: No. A relative or other non-parent can ask the Juvenile Court for legal custody of a child under R.C. 2151.23 / 2151.353 when living with a parent is not in the child's best interest; the court weighs the child's best interest and whether a parent is unsuitable. Legal custody does not permanently end the parents' rights or support duty. Adoption (a Probate matter) permanently transfers parentage, and guardianship is a separate Probate process.
How much does it cost to file for custody or paternity in Miami County Juvenile Court?: The Juvenile Court charges $135.00 per child for a paternity, allocation of parental rights (custody), or visitation petition, due at filing, plus $2.00 per subpoena issued. No filing fee is charged to the Miami County CSEA or Children's Services Board (Local Juv. R. 4.06). Court costs are assessed at final disposition, and an indigency application may be filed to seek a waiver (Local Juv. R. 4.02–4.03).
When does Miami County appoint a Guardian ad Litem?: In a contested custody case, the court can appoint a Guardian ad Litem (GAL) — a court-appointed attorney who investigates and recommends what is in the children's best interest, often in a written report filed before the merit hearing. The GAL represents the child's best interest, not the child's stated wishes. GAL fees are typically allocated between the parents at the court's discretion.
How does a Miami County court decide custody?: R.C. 3109.04(F)(1) lists 10+ factors: each parent's wishes, the child's wishes (when of sufficient age), the child's interaction with parents/siblings, adjustment to home/school/community, mental and physical health of all involved, the parent more likely to facilitate court-approved parenting time, child support compliance, criminal history, residence outside Ohio, and any history of abuse.
