    Affidavit of Support vs Net Worth Certificate: Who Files What

    An affidavit of support is the sponsor's sworn promise to pay. A net worth certificate is a chartered accountant's signed statement of what the sponsor owns and owes on a date. One speaks to willingness, the other to ability, and that is why visa files so often carry both. This guide explains who signs, swears and stamps each one, what an Indian notarised affidavit really commits you to, and when the affidavit alone will do.

    Two papers, two speakers

    The difference is who is speaking, and about what.

    One is a sponsor's sworn promise, the other is a CA's attested figure

    Put the two documents side by side and the difference is who is speaking.

    • In an affidavit of support, the sponsor speaks about what they will do.
    • In a net worth certificate, a chartered accountant speaks about what the records show.

    That changes what each one can be wrong about.

    The affidavitA promise can be entirely sincere and still failBecause circumstances change.
    The certificateA statement of position can be accurate on its dateAnd say nothing about next year.

    Neither weakness is a defect. They are different instruments doing different work.

    The subject differs too.

    The affidavitAlways the sponsorWhatever figures it recites
    The certificateThe sponsorThe applicantEach of them, in a separate document

    An affidavit is always about the sponsor, whatever figures it recites. A certificate is about whoever the accountant examined. Files carry both because the two papers answer different questions, and neither stands in for the other.

    Who signs, who swears and who stamps each one

    This is where the two stop resembling each other.

    The affidavit

    Sworn by the sponsor

    • Signed byThe sponsor (the deponent).
    • Sworn beforeUsually a notary or an oath commissioner, who administers the oath and typically adds a seal and signature.
    • The paperUsually executed on stamp paper. The value depends on the stamp law of the state where it is executed, so the same undertaking can be sworn on paper of different value in different states.
    • DatedThe day it is sworn, and speaks from that day.
    The net worth certificate

    Signed by a chartered accountant

    • Signed byA chartered accountant in practice, personally or for a firm.
    • IdentifiersUsually carries identifiers that all point outward: the member's name and membership number, the firm registration number where the firm signs, the place, the date, and a unique document identification number for that certificate.
    • DatedStates an "as on" date for the position, which can be earlier than the date of signature. Both dates on its face are real, and both matter.
    The notary's seal proves that an oath was administeredIt does not certify that what was sworn is true, and it was never meant to.
    The accountant's signature makes a different claimThat records were examined and the figures follow from them.A reader who wants to test that claim has somewhere to go.

    An affidavit binds the person who swore it to the truth of what they said. On its own, it does not create a debt owed to the applicant or a right the applicant can enforce. What it creates is exposure.

    Bharatiya Nyaya Sanhita, 2023 · in force 1 July 2024

    A person bound by oath who makes a statement they know to be false is giving false evidence.

    Section 227Giving false evidenceDeals with the statement itself.
    Section 229Sets the punishment
    Up to seven yearswhere the false evidence is given in a judicial proceeding
    Up to three yearsin any other case

    Whether the undertaking can be enforced against the sponsor abroad is a separate question. Reading an Indian affidavit from abroad can add one more step.

    Enforceability abroadDepends on the law of the destination countryNot on Indian law, so read the route's own guidance.
    AuthenticationA foreign authority cannot check an Indian notary's seal against anything it holdsSo the document may need to be authenticated before it is accepted. Which form of authentication applies depends on the destination; check the mission's own document requirements before you swear it.
    Strong on intention, silent on capacity

    The practical effect is that an affidavit is not weak; it is narrow. Treating it as evidence of means is the error behind many refusals that applicants later describe as unfair.

    Why sponsors are usually asked for both

    In practice the two papers are read as one set, alongside the sponsor's bank statements and tax returns. The evidence bundle a sponsor files is read for agreement between its parts before any single part is read on its own.

    Disagreement is costly.

    The affidavitRecites a figureA number typed into the undertaking.
    The certificateDoes not support itThe examined position says something else.

    An affidavit that recites a figure the certificate does not support is worse than an affidavit with no figure in it, because it turns a gap into a contradiction.

    The checks applied to sponsor papers are the same checks applied to the applicant's, with the relationship added, so a contradiction tends to surface rather than pass quietly.

    Where only one document is asked for, which one tells you what the route is testing:

    A route that names a sponsor and wants their undertakingIs testing responsibility

    The affidavit is the paper it reads.

    A route that wants an assessment of the sponsor's meansIs testing capacity

    And the amount the file must cover is then the number under examination.

    Either way, the sponsor's own evidence carries the weight

    An undertaking with nothing behind it is the one combination that reliably fails, and it fails on the first reading.

    Drafting the sponsorship undertaking without overcommitting

    Scope decides the sponsor's real exposure, and it is often settled without much thought. This section explains what to look at; it is not legal drafting advice, and the wording of your undertaking is for you and your adviser.

    1. Scope
      BoundedAn undertaking limited to named costs, for a named person, over a named period, is a bounded commitment.
      Bounded by nothingAn undertaking to "meet all expenses for the duration of the stay".
    2. Duration
      StatedA course runs for a stated number of years, and the undertaking can say so.
      SilentIf it is silent on duration, the endpoint is left to be argued about later, and where the destination treats the undertaking as recoverable, that argument has a cost.
    3. Generality

      Open-ended exposure usually enters through broad wording rather than a specific promise.

      Reaches too farWording that reaches "any liability the applicant may incur" reaches much further than most sponsors intend. So does an undertaking given jointly with someone whose finances the sponsor has never seen.
    4. Consistency
      One factAny figure the affidavit recites should be the certified figure, on the certified date, described the same way.
      Two documents, no factIf the affidavit says one thing and the certificate another, the reader has two documents and no fact.

    Where the sponsor's money originates should tell the same story in both papers. A sponsor who cannot explain the source of what they have undertaken to spend has answered only half the question.

    Verdict: when an affidavit alone will carry the application

    There is a real set of files where the affidavit is enough on its own.

    Enough on its own, all three together
    A short visit with modest costsThe stay is brief and the money involved is small.
    A sponsor paid by salaryThe means are visible in the sponsor's own statements.
    A route that asks only for an undertakingAnd the sponsor's own bank statements, nothing more.

    In that file, a certificate answers a question nobody asked.

    A certificate becomes necessary in three situations:

    1. Capacity cannot be read off a bank statementWealth held in deposits, property and investments across several institutions does not present itself. It has to be put together and attested by someone who examined it.
    2. The route asks for an assessment of meansNot just a balance.
    3. The papers are too many to readWhere a sponsor's records are numerous, in several formats, and partly in a language the mission does not read, one attested schedule replaces a folder.

    Having the sponsor's position attested is worth doing in those cases. It is not worth doing where the route has not asked for it and the statements already speak for themselves.

    Whether an Indian affidavit can be enforced abroad, and what authentication a destination asks for before it reads one, are decided by that destination's own rules; this guide names neither a route nor a procedure. Read the mission's own document requirements before you swear the undertaking.
