Can your business partner withdraw funds without your consent? For ordinary, legitimate business expenses, usually yes; for personal use or anything outside the ordinary course of the business, almost never. What controls the answer is your partnership agreement, the default rules of your state’s partnership law, and the fiduciary duties every partner owes regardless of what’s on paper. If your partner has already moved money to a personal account or spent it on themselves, you likely have grounds for civil claims, and in serious cases criminal ones.
Start With the Partnership Agreement
If you have a written agreement, that document controls. It should say who can spend money, how much, and under what circumstances. Well-drafted agreements include caps on individual spending authority, dual-approval requirements above certain dollar amounts, rules about draws against profits, and restrictions on transfers to personal accounts. A withdrawal that violates any of those provisions is a breach of contract.
Specificity is what makes the agreement useful. “Withdrawals over $5,000 require both partners’ signatures” is enforceable. “Partners should consult each other on major expenses” is something to argue over. If your agreement is thin, or if you never put one in writing, a partner’s unauthorized withdrawal is usually the moment that gets fixed.
What State Law Allows When There’s No Agreement
Many partnerships operate without a written agreement. When that’s the case, state law fills the gaps, and most states have adopted some version of the Revised Uniform Partnership Act.
Under those default rules, every partner has equal rights to manage the business, including access to partnership funds for legitimate business purposes. Your partner doesn’t need your permission for every routine expense. But the law draws a sharp line: any act outside the ordinary course of business requires the consent of all partners. Paying a supplier invoice is ordinary. Wiring $50,000 to a personal account is not.
Profits and losses are shared equally under the default rules unless the partners have agreed otherwise. Even if your partner claims the withdrawal was their “share” of profits, they can’t unilaterally decide when or how to take a distribution. Partnership property belongs to the partnership, and a partner can only use it on the partnership’s behalf.
Fiduciary Duties Apply Either Way
Written agreement or not, every partner owes fiduciary duties to the partnership and to every other partner. These aren’t optional courtesies. They’re legal obligations enforceable in court, and the two core ones are loyalty and care.
Duty of Loyalty
The duty of loyalty requires a partner to put the partnership’s interests above their own. A partner must account to the partnership for any property, profit, or benefit derived from using partnership resources, cannot deal with the partnership as an adversary, and cannot compete against it. Taking company money for personal use is textbook self-dealing. A partnership agreement can shape the boundaries of loyalty, but it cannot eliminate the duty entirely, and courts will refuse to enforce limitations they find unreasonable.
Duty of Care
The duty of care requires each partner to act as a reasonably careful person would in a similar position. The bar is not perfection. It’s the avoidance of grossly negligent, reckless, or intentionally harmful conduct. A partner who empties the operating account without checking whether payroll clears may have breached this duty even if the money went to a legitimate expense.
The Legal Claims You May Have
When a partner takes funds without authorization, several claims come into play. Which ones fit depends on the facts.
Breach of Contract
If the withdrawal violates a specific term in your partnership agreement, breach of contract is the most direct claim. You show the agreement, point to the violated provision, and prove the financial harm. Damages aim to put you back where you would have been had the agreement been honored.
Breach of Fiduciary Duty
This claim doesn’t require a written agreement. You show that the partner owed fiduciary duties, that they violated them, and that the violation caused financial harm. Remedies can include compensatory damages, disgorgement of any profits the partner gained from the breach, and in some cases injunctive relief preventing further misconduct.
Conversion
Conversion is the civil equivalent of theft. It applies when someone intentionally takes or exercises control over property belonging to someone else. A partner who transfers partnership funds to a personal account without authority has converted partnership property. The partner doesn’t need to know the conduct is illegal; the intent to possess or control the property is enough.
Criminal Embezzlement
When the amounts are significant or the conduct is egregious, unauthorized withdrawals can cross into criminal territory. Embezzlement is the theft of assets by someone in a position of trust over those assets, and a partner with signatory authority who siphons money for personal use fits that definition. Criminal prosecution is separate from any civil lawsuit and can result in imprisonment and fines that scale with the amount taken. Whether a prosecutor pursues charges depends on the evidence and the jurisdiction, but filing a police report creates a record that can also strengthen your civil case.
What to Do Right Now
Speed matters. If your partner has already taken money without authorization, assume it can happen again. The steps below should happen quickly, and to the extent possible, in parallel.
Secure the Financial Records
Gather every financial document you can access: bank statements, accounting software records, canceled checks, wire transfer confirmations, credit card statements, and tax returns. Make copies and store them somewhere the other partner cannot reach. If your partner controls the books and you’re worried about alteration, a forensic accountant can reconstruct transaction histories independently from bank records.
Put the Demand in Writing
Contact your partner by email or another written channel. Ask for an explanation and demand the immediate return of the funds. Keep the tone factual. Everything you write may end up in front of a judge, and you want it to show that you acted reasonably while your partner did not. Avoid verbal conversations about the dispute, and if any happen, follow up with an email summarizing what was said.
Restrict Account Access
Contact your bank about changing the signature requirements on partnership accounts. Banks typically need authorization from an existing signatory to modify access, and you may be able to add a dual-signature requirement so that no single partner can withdraw alone. Keep in mind that banks follow whoever is listed as an authorized signer, not your internal agreement. If your partner is on the account, the bank is not liable for honoring their withdrawals even when those withdrawals violate your agreement. Changing the authorization is on you.
Ask a Court to Freeze Assets If Needed
If your partner appears to be actively draining accounts, an attorney can file for a temporary restraining order or preliminary injunction to freeze partnership assets. Courts grant this when you can show that irreparable harm will occur without immediate intervention. It’s the strong remedy, but when money is walking out the door, waiting for a full trial is not practical.
Consult a Business Litigation Attorney
An attorney experienced in partnership disputes can read your agreement, explain your rights under your state’s law, and lay out your options, which may range from a formal demand letter to mediation to filing suit. Fees vary, but the initial consultation should tell you whether the amount at stake justifies the cost of legal action.
Formal Accounting and Dissolution
Partners have a legal right to a full accounting of partnership finances. An accounting is a court-supervised review of all partnership transactions, designed to determine where the money went and what each partner is owed. Courts are most likely to order one when the records are complex, when partners disagree about their respective shares, or when there are accusations of misconduct that require an independent assessment. An accounting can reveal patterns of self-dealing that a quick review of bank statements would miss.
Sometimes the trust is too broken to continue. Courts can order dissolution when a partner has engaged in conduct that materially harms the business, persistently violates the partnership agreement, or makes it no longer reasonably practicable to carry on together. Dissolution triggers a winding-up process where assets are liquidated, debts are paid, and remaining funds are distributed. Court supervision ensures that the partner who caused the problem does not also control the exit. If you want to keep the business alive without the offending partner, some jurisdictions allow you to seek a judicial expulsion instead, removing the partner while the business continues.
A Note on LLCs and Corporations
The rules above are for general partnerships. Many people who say “business partner” actually co-own an LLC or a corporation. The principles carry over, since fiduciary duties and contractual obligations exist in those structures too, but the specifics differ. In an LLC, the operating agreement replaces the partnership agreement and state LLC statutes replace the partnership act as the default rules. Members generally cannot make distributions without following the operating agreement’s procedures, and managers owe fiduciary duties comparable to those in partnerships. If your business is an LLC or corporation, the analysis still starts with your governing documents and state law, but details vary enough that advice specific to your entity type is worth getting early.
