The first move matters more than any other step: secure the records before saying anything to the partner. A partner who suspects theft and confronts the other partner first, or locks them out of the bank account first, usually loses access to exactly the evidence that would have proven the case, and may hand the other side a counter-claim of their own. Section 403(b) of the Uniform Partnership Act (1997) gives every partner a right to inspect and copy the partnership's books and records; that right is the starting point, not a demand letter and not a confrontation.

What follows is the order that protects a partner who is right, and limits the damage if they turn out to be wrong about the scale of it (a partner who is sloppy with expense reporting is not the same as a partner who is stealing, and the first few steps are what tells the difference).

The order, step by step

What to do, in order

  1. Preserve the records before doing anything else

    Make copies, offline, of bank statements, QuickBooks or other accounting files, invoices, contracts, and any correspondence that might be relevant. Do this before confronting the partner or changing any account access; a partner who is actually taking money can delete or alter records once they know they are suspected.

  2. Exercise the statutory right to inspect the books

    Section 403(b) entitles a partner to inspect and copy the partnership's books and records during ordinary business hours. Put the request in writing and keep a copy, even where access is not actually being refused; it establishes the date and creates a paper trail.

  3. Bring in a forensic accountant before drawing conclusions

    An irregular pattern in the books is not proof, and an accusation that turns out to be wrong over a bookkeeping error is expensive and hard to undo. A forensic accountant who specializes in small-business disputes can trace specific transactions and distinguish sloppy recordkeeping from actual diversion.

  4. Check who can move money, and change it if needed

    On a joint account, either signer can usually withdraw or transfer funds unilaterally; this is a banking rule, not a partnership one, and it is why a partner who suspects ongoing theft often needs the bank's help (a second-signature requirement, a lowered transfer limit) rather than a legal filing to stop the bleeding immediately.

  5. Send a written demand

    Once the accountant's findings support it, a formal demand for an accounting or repayment puts the other partner on notice and starts building the record a court will eventually want to see, whether or not it is ever filed.

  6. Bring an accounting action if the demand does not resolve it

    Section 405(b) lets a partner sue the partnership or another partner for an accounting, with or without dissolving anything, to enforce rights under sections 401, 403 or 404. This is the formal version of asking a court to work out exactly what is owed.

  7. Consider expulsion once the facts are established

    A court may expel a partner for wrongful conduct that materially harmed the business, or for a willful, persistent breach of the duties in section 404 (section 601(5)). An expelled partner is still owed a buyout under section 701, reduced by what they took (section 701(c)); expulsion is a remedy, not a way to avoid paying anything at all. See how to remove a business partner for the mechanics.

Records to pull together before talking to anyone

  • Twelve months of bank and credit card statements for every partnership account
  • The accounting software file or a full export of the general ledger
  • Every signed contract, lease and loan the partnership is party to
  • Payroll records, including any payments to the suspected partner or their family
  • Vendor invoices next to the payments actually made against them
  • Any side businesses or vendors the suspected partner has an undisclosed interest in
  • Email and messages referencing money, invoices or vendor relationships

Why moving money yourself is also a breach

Civil action, not automatically a crime

An accounting action under section 405 and expulsion under section 601(5) are civil remedies, available regardless of whether anything rises to criminal embezzlement. Whether a partner's conduct is also a crime, and what has to be proven for that, is a question of the specific state's criminal code, and it varies enough state to state (how clearly the money has to have been entrusted to the partner, what dollar threshold separates a misdemeanor from a felony, whether a partner taking from a business they co-own is treated the same as an employee taking from an employer) that this guide does not attempt to generalize it. A lawyer in the partnership's state, not this page, should be the one to say whether a specific pattern of conduct also warrants a police report.

What is consistent across states is that a civil accounting action does not require proving intent to the criminal standard, and does not wait on a prosecutor's decision to bring charges. A partner who wants their money back, as opposed to wanting the other partner punished, usually gets there faster through sections 403 and 405 than through a criminal referral. This is general information on the uniform partnership act, not legal advice; a lawyer should be involved before any formal action is taken.
