What is 154?
The Affidavit of Parentage (Fill-In Form) is a Delaware Family Court form on which a petitioner or respondent states, under penalty of perjury, what they know about who is a parent of a named child, so the court can see who else may have a legal connection to the child.
The caption names the Family Court of the State of Delaware, with the county (New Castle, Kent or Sussex), the petitioner and respondent, and the child: "in the interest of", date of birth, and city and state of birth.
The numbered paragraphs ask:
- Paragraph 1: who the child's birth mother is (petitioner, respondent or other, with an address if other).
- Paragraph 2: whether court- or agency-ordered genetic testing has never been conducted, may have been conducted with an unknown result, excluded someone as a parent, or established someone as a likely parent by a 99% or greater probability.
- Paragraph 3: anyone identified as a parent by a court or administrative order, who signed a Voluntary Acknowledgement of Paternity (VAP) on file with an Office of Vital Statistics, who is named on the birth registration, who took part in assisted reproduction intending to become a legal parent, or who lived in the same household and held the child out as their own for the first 2 years of the child's life.
- Paragraph 4: whether the child was born during a marriage or civil union, or within 300 days after divorce or dissolution.
- Paragraph 5: name and address of anyone from paragraph 3 or 4 who is not already a party to the petition.
- Paragraphs 6 and 7: completed only by the child's mother.
The form is sworn before a notary or the Clerk of Court.
Who needs to file 154?
The form is completed by a party to a Family Court matter about a child's parentage, shown on the form as the petitioner or the respondent. The caption asks you to mark which one you are.
- Any petitioner or respondent: answer paragraphs 1 through 5 and sign the oath.
- The child's mother: also answer paragraphs 6 and 7, which sit under the heading "Complete only if you are the child's mother". They ask who she believes the biological father is and whether that person was the only person with whom she had sexual intercourse, or whether she conceived by assisted reproduction with an anonymous sperm donor. She may instead choose not to answer and ask that genetic testing be ordered to determine parentage.
- Anyone who is not the mother: leave paragraphs 6 and 7 blank, as the heading directs.
Paragraph 5 asks you to name any person identified in paragraph 3 or 4 who is not already a party to the petition. The form does not say who may sign for another person; it asks for the signature of the petitioner or respondent.
When to file 154
The affidavit refers to "this petition", so it is completed in connection with a petition in the Family Court and not on its own schedule. The form prints no separate due date. Complete it when you prepare or respond to that petition, using what you know at the time, and sign it before a notary or the Clerk of Court. For deadlines that apply to your petition, check the Family Court's instructions or ask the court.
How to fill out 154
Complete the court heading
Select the county (New Castle, Kent or Sussex) and mark whether you are the Petitioner or the Respondent. Enter the child's name after "In the interest of", plus date of birth and city and state of birth.
Identify the birth mother in paragraph 1
Mark whether the child's birth mother is the Petitioner, the Respondent or Other. If you mark Other, provide her address.
Report genetic testing in paragraph 2
Check the box that fits testing ordered by any court or state agency: never conducted, may have been conducted with an unknown result, excluded as a parent, or established as a likely parent by a 99% or greater probability.
Identify people listed in paragraph 3
For each statement, write the name of the person it applies to, or "not applicable" or "unknown". The statements cover a court or administrative order, a signed Voluntary Acknowledgement of Paternity (VAP), the birth registration, assisted reproduction, and living in the same household for the child's first 2 years.
Answer the marriage questions in paragraph 4
Mark YES, NO or UNKNOWN for birth during a marriage or civil union or within 300 days after divorce or dissolution. If yes, name the mother's spouse or ex-spouse and answer the two follow-up questions.
Name other people in paragraph 5
Enter the name and address, if known, of anyone identified in paragraph 3 or 4 who is not already a party to this petition.
Answer paragraphs 6 and 7 if you are the mother
Name the person you believe is the biological father, then check the one statement in paragraph 7 that applies. Skip both paragraphs if you are not the child's mother.
Sign and print your name
Sign as petitioner or respondent under the oath. An electronic signature is permitted; enter "/s/ Your Name" and print your name.

How to submit 154
The form names no filing channel, address or portal of its own. It refers to "this petition", so it goes to the Family Court with the petition it supports; confirm the county's filing method with the court.
- Signing: the oath says "I SWEAR (or) AFFIRM under penalty of perjury". The form states that an electronic signature is permitted: sign "/s/ Your Name" and print your name.
- Swearing: the bottom block, "Sworn to and subscribed before me", has spaces for the day and date and for the signature of a Notary or the Clerk of Court.

Common mistakes to avoid
- Leaving the county line blank when the caption asks for New Castle, Kent or Sussex County.
- Completing paragraphs 6 and 7 when you are not the child's mother; the form says to complete them only if you are.
- Answering paragraph 3 with a blank line instead of naming a person or writing "not applicable" or "unknown".
- Not marking in paragraph 2 whether genetic testing has never been conducted, may have been conducted with an unknown result, excluded or established someone.
- Skipping the follow-up questions in paragraph 4 when you answer "yes" to birth during a marriage or civil union or within 300 days after divorce or dissolution.
- Omitting the name and address of a person from paragraph 3 or 4 who is not yet a party to the petition, as paragraph 5 asks.
- Signing without a printed name, or not using the "/s/ Your Name" format when signing electronically.
- Leaving the notary or Clerk of Court block unsigned after swearing to the statement.
Frequently asked questions
What is an affidavit of parentage in Delaware Family Court?
It is a sworn statement on a Delaware Family Court form in which a petitioner or respondent gives facts about a child's parentage: the birth mother, genetic testing, other possible parents and any marriage at the time of birth. It is signed under penalty of perjury.
Who has to complete the affidavit of parentage?
The form is completed by the petitioner or respondent in the Family Court matter. Only the child's mother answers paragraphs 6 and 7, which the form marks "Complete only if you are the child's mother".
Does the affidavit of parentage need to be notarized?
The form ends with a "Sworn to and subscribed before me" block with a line for a Notary or the Clerk of Court, so it is sworn before one of them. Your own signature may be electronic, written as "/s/ Your Name".
Can I fill out the affidavit of parentage online?
Yes. You can fill out the PDF online on FillingPDF and download or print it. FillingPDF is an independent service and does not file it with the Family Court; you submit it through the court's channels.
What if I am not sure who the father is?
Paragraph 7 lets the mother mark that the named person was not the only person with whom she had intercourse, or that she conceived by assisted reproduction with an anonymous sperm donor. She may also decline to answer and ask that genetic testing be ordered.
What does paragraph 3 of the affidavit ask?
It asks you to name any person identified as a parent by a court or administrative order, who signed a Voluntary Acknowledgement of Paternity, who is on the birth registration, who took part in assisted reproduction intending to be a parent, or who lived with the child for the first 2 years. Write "not applicable" or "unknown" if none applies.
What do I enter if the child was born during a marriage?
Mark YES in paragraph 4, then give the name of the birth mother's spouse or ex-spouse and answer whether he or she openly held the child out as their own, and whether the mother and husband cohabitated or had intercourse during the probable time of conception.
