The Signature You Do Not Remember Giving

Somewhere in the stack of documents you signed to receive the advance, there was a personal guarantee. You may not have read it. You almost certainly did not negotiate it. The broker or funding representative may have described it as standard, or routine, or something that never gets enforced. It was none of those things. A personal guarantee is a separate promise, made by you as an individual, to repay the debt if your business cannot. It transforms a business obligation into a personal one, and the transformation is, in most cases, exactly as serious as it sounds.

The Guarantee Extends Beyond the Business

The first thing to understand is scope. A personal guarantee on an MCA agreement means the funder can pursue your personal assets if your business defaults. This includes personal bank accounts, real property, vehicles, and in some jurisdictions, wages. The corporate veil that separates your business from your personal finances does not apply to debts you have personally guaranteed. You signed it away.

This does not mean enforcement is automatic. The funder must obtain a judgment against you personally before seizing personal assets. In states that still permit confessions of judgment, that process can be alarmingly fast. In others, the funder must file a lawsuit, serve you, and prevail in court. The timeline matters. The gap between default and personal enforcement is the window in which negotiation occurs, and it closes more quickly than most people realize.

Limited and Unlimited Are Not the Same Document

The second thing to know is whether your guarantee is limited or unlimited. A limited personal guarantee caps your exposure at a specific dollar amount. An unlimited guarantee does not. The difference between these two documents is the difference between a difficult financial situation and a catastrophic one.

Pull the agreement. Find the guarantee provision. If it contains a stated maximum amount, your personal exposure has a ceiling. If it does not, the funder can theoretically pursue you for the entire outstanding balance, plus fees, plus legal costs, plus whatever the confession of judgment authorized. I have reviewed MCA agreements where the personal guarantee exceeded the original advance by a factor of three, once all the accelerated fees and penalty provisions were calculated.

The number on the guarantee is not always the number you owe. But it is the number the funder will claim.

Enforcement Requires a Judgment

The third thing is procedural, and it offers more protection than most business owners realize. A personal guarantee, standing alone, is a promise. To enforce that promise, the funder must convert it into a court judgment. In states where the confession of judgment has been restricted or banned for out‑of‑state defendants (New York amended CPLR Section 3218 in 2019 to prohibit this), the funder must file a traditional lawsuit. That lawsuit requires service of process, an opportunity to respond, and, if contested, a hearing or trial.

This means time. And time, in MCA default situations, is the most valuable asset available. An attorney can use the litigation timeline to negotiate a settlement on the personal guarantee at a fraction of the claimed amount. Funders know that litigation is expensive. They also know that a personal guarantee is only worth what they can collect, and collection against a personal guarantor who is represented by counsel and disputing the underlying agreement is substantially more difficult than collection against an unrepresented business owner who does not respond.

The Guarantee May Be Challengeable

The fourth thing is the possibility most business owners never consider: the personal guarantee may not be enforceable. If the underlying MCA agreement is found to be a loan (rather than a purchase of future receivables), and if the effective interest rate exceeds the state’s usury cap, the entire contract may be void. A void contract cannot support an enforceable guarantee. Courts in the Southern District of New York and in Westchester County have vacated confessions of judgment and voided MCA agreements on precisely these grounds, holding that where the funder’s practices demonstrated no genuine contingency in repayment, the instrument was a loan subject to usury laws.

The guarantee sits on top of the agreement. If the foundation is defective, the guarantee does not stand on its own.

The Conversation You Need to Have at Home

The fifth thing is not legal. It is personal. If you signed a personal guarantee on an MCA, your spouse or partner needs to know. Not eventually. Now. In community property states, assets acquired during the marriage may be reachable by a judgment creditor. In common law states, jointly held property may also be at risk. The specific exposure depends on your state, the nature of the guarantee, and how your assets are titled, but the general principle is straightforward: a personal guarantee makes this a household problem, not merely a business one.

There is a particular silence in a conference room at the end of a long mediation, after the settlement terms have been discussed and the guarantor realizes what the number means for the family’s savings account. That silence is avoidable. It requires a conversation now, not after the funder files.

A consultation with an attorney who handles MCA personal guarantees is where clarity begins. The guarantee is a document. Documents have weaknesses. The question is whether anyone examines yours before the funder acts on it.
