An Affidavit of Birth is a sworn statement establishing the facts of a person's birth. It is used when a PSA birth certificate is unavailable, when birth registration was delayed, or when the existing record contains errors that need to be supported by sworn testimony. Government agencies, the Local Civil Registry, schools, and courts regularly require this document as part of civil registration and identification processes.
Legalia automates the drafting. This tutorial walks you through the complete process of generating a notary-ready Affidavit of Birth online — from logging in to saving a print-ready PDF — in five steps.
What you need before you start
- A free Legalia account — sign up here
- The affiant's full name, civil status, address, and relationship to the subject (parent, sibling, or relative)
- The subject's full name, date of birth, place of birth, father's name, and mother's name
- The purpose for which the affidavit is being executed
Step 1: Log In and Open Your Dashboard
Sign in to your Legalia account at https://legalia.ph. After logging in you will land on the document library dashboard, which lists all available document types grouped by category — Affidavits, Contracts, Deeds, and more.
Step 2: Select Affidavit of Birth
Under the Affidavits category, click Affidavit of Birth. The document editor opens in a two-panel layout:
- Left panel — the guided form with all required and optional fields
- Right panel — the live document preview, updated in real time
Every change you make in the form is immediately reflected in the preview — you always see exactly what will print.
Step 3: Fill In the Form
Complete the fields on the left panel. The form is divided into three sections:
Affiant Information
| Field | Notes |
|---|---|
| Full Name | Exactly as it appears on a government-issued ID |
| Civil Status | Single / Married / Widowed / Legally Separated |
| Address | Complete residential address including barangay, city/municipality, and province |
| Relationship to Subject | Describe the relationship — e.g., "parent," "elder sibling," "relative," or "attending physician" |
Subject's Information
| Field | Notes |
|---|---|
| Full Name | Subject's complete legal name |
| Date of Birth | Exact date; for delayed registration this establishes the age at the time of registration |
| Place of Birth | Municipality/city and province where the birth occurred |
| Father's Name | Subject's father's full legal name |
| Mother's Name | Subject's mother's full legal name (maiden name preferred) |
Purpose
| Field | Notes |
|---|---|
| Purpose | State the reason the affidavit is being executed — e.g., "for delayed birth registration," "in lieu of a lost PSA birth certificate," or "to support a government benefit application" |
Step 4: Review the Live Preview
The right panel shows the document exactly as it will print. Review the full text carefully — especially the affiant's statement of knowledge, the subject's birth facts, and the jurat block at the bottom.
The following optional tool appears at the top of the preview panel:
- Polish with AI — rewrites the narrative paragraphs in formal legal Philippine English while preserving all facts. Useful when the information was provided in informal language.
Step 5: Print or Save as PDF
When the document looks correct, click the Print button in the action bar. Your browser's print dialog opens.
- To print on paper: select your printer and click Print.
- To save a PDF: change the Destination to Save as PDF. The output is a clean document with no UI chrome, headers, or footers — formatted for standard 8.5×11 or A4 paper with correct margins and line spacing for notarial use.
Bring the printout to your commissioned notary public for the affiant's oath and signature.
That is the complete workflow — from opening the dashboard to a notary-ready Affidavit of Birth.
