Cost to Adopt Someone Over 18: Adult Adoption Costs in the United States

Legal Guide Team

Adult adoption offers a legal pathway to recognize an established parental relationship, remove barriers to inheritance, and formalize a family bond. While costs are generally lower and less burdensome than child adoptions, they vary by state and case specifics. This article explains typical expenses, how state laws influence pricing, and practical tips to minimize costs when adopting an adult.

Understanding Adult Adoption Basics

Adult adoption is the legal process through which a person 18 years or older becomes the child of another adult in a legally binding parent-child relationship. Unlike juvenile adoptions, adult adoptions usually do not require a home study, post-placement supervision, or a series of visits. The primary requirements focus on consent, proof of the adoptive relationship, and the absence of impediments to the adoption.

Key factors that shape the cost include filing fees, attorney fees, and optional steps such as name changes or certified copies. Since both parties are adults, the process is typically simpler, faster, and less costly in many jurisdictions than adopting a minor.

Typical Cost Breakdown

The total cost to adopt someone over 18 varies, but most cases fall within a predictable range. The breakdown below reflects common components across many states:

  • Court Filing Fees: Fees to file the petition and related documents. Typical range: $100–$400.
  • Attorney Fees: Legal representation is common to ensure proper petitions, waivers, and filings. Typical range: $500–$2,000 for straightforward adult adoptions; complex cases may exceed $2,000.
  • Home Study or Background Checks: For adults, a home study is usually not required. Some jurisdictions may still require a background check or simple verification of identity. Typical range: $0–$300 if required.
  • Name Change Fees: If the adoptee requests a legal name change, additional filing fees apply. Typical range: $150–$500.
  • Certified Copies: Official copies of the final judgment and amended birth or records. Typical range: $10–$40 per copy.
  • Publication or Notice: Some states require notice to certain parties or publication in a newspaper, though this is uncommon for adult adoptions. Typical range: $0–$100 if required.
  • Administrative or Miscellaneous Costs: Notary fees, service costs, and handling fees. Typical range: $0–$100.

Overall, a typical adult adoption can cost between $300 and $3,000, with the majority of straightforward cases landing in the $1,000–$2,000 range when using an attorney. In states where no attorney is required, costs can be on the lower end, but self-representation may introduce delays or complications.

State Variations That Affect Price

State laws significantly influence the cost and process of adult adoptions. Some common variations include:

  • Requirement for Home Studies: Most states do not require a home study for adults, reducing costs. A few jurisdictions may still request a simple home assessment or interview.
  • Consent Rules: An adult can usually consent freely, but some states require the other party’s consent to be witnessed or notarized.
  • Petition and Clerk Fees: Filing fees differ by state and can vary based on county.
  • Publication and Notice: A minority of states require notice to certain relatives or publication, adding additional steps and costs.
  • Name Change Provisions: If a name change accompanies the adoption, this adds separate filing fees that differ by state.

To get precise figures, prospective adopters should consult the state’s family court website or speak with a local family law attorney who specializes in adult adoptions. The variance across jurisdictions is often the largest single driver of total cost.

  • Choose Self-Representation When Allowed: If the court allows, filing petitions without an attorney can save substantial fees, provided the process remains straightforward.
  • Ask About Flat Fees: Some attorneys offer flat-rate packages for simple adult adoptions, which helps with budgeting.
  • Prepare Thorough Paperwork: Submitting complete, accurate forms reduces the risk of delays and additional court filings.
  • Plan for Name Change Separately: If a name change is desired, compare costs for separate filing versus bundled services with an attorney.
  • Check Free or Low-Cost Legal Aid: Some nonprofit organizations offer low-cost or pro bono services for family law matters in certain states.
  • Clarify Court Delays: Court calendars vary; understanding typical wait times can help budget for potential delays or additional filings.

Process Steps And Timeline

While specifics vary by state, the general process follows a common sequence:

  1. Confirm Eligibility: Verify that both parties are adults and that there are no legal barriers to adoption.
  2. Prepare Petition: Gather necessary information about the adoptee, the petitioner, and any requested name change.
  3. File Petition and Pay Fees: Submit to the appropriate family or probate court and cover filing costs.
  4. Notice Or Consent: Ensure any required notices or consents are completed and filed.
  5. Attend Hearing: A court appearance is typically scheduled to review and grant the adoption, often with both parties present.
  6. Obtain Final Judgment: After the judge issues the final decree, obtain certified copies of the judgment and, if applicable, amended birth records and name changes.

In straightforward cases, the court process can take a few weeks to a few months, depending on court backlogs and the need for any additional documentation. Preparation and early planning help minimize delays and additional costs.

Common Pitfalls And How To Avoid Them

Anticipating potential issues can prevent costly delays:

  • Unclear Relationship Evidence: Provide clear documentation or declarations demonstrating the enduring relationship to avoid requests for additional proof.
  • Missing Consent Documentation: Ensure all required consents are properly witnessed or notarized per state rules.
  • Inaccurate Personal Information: Double-check names, dates of birth, and identification numbers to prevent court delays.
  • Incorrect Fees: Verify current filing and ancillary fees with the court to avoid surprise costs.
  • Assuming No Name Change: If a name change is desired, plan for the separate process and associated fees rather than assuming it’s included.

By understanding state-specific requirements and preparing thoroughly, adoptive adults can achieve a smooth, cost-efficient process that formalizes family ties without unnecessary financial strain.
