The personal guaranty in your MCA

What a guaranty is, how a performance guaranty differs from a payment guaranty, how to find yours and what to ask before signing.

You signed for your company. Then you signed again, as yourself. That second signature is often the personal guaranty, and it decides who the funder can turn to if things go wrong.

What it is

A personal guaranty is a promise by an owner, in their own name, that the business will keep certain promises. It may be a separate page or a section of the main agreement. Funders ask for one because a company can be closed and an owner is harder to walk away from.

The key point is that the guaranty is its own contract. It can have its own terms, its own definition of what you are promising, and its own waivers. Read it as carefully as the main agreement.

Two kinds

Many MCA guaranties fall into one of two broad types. The labels vary, so look at what the text actually says.

Performance (validity) guarantyPayment guaranty
What it promisesThat the business and owner will not do certain bad acts, such as lying, diverting receivables, blocking debits or closing the business to avoid the deal.That the funder will be paid the unpaid amount if the business does not pay it.
Usually triggered byA listed act or breach of a promise.Non-payment or default of the business.
If the business simply has low salesOften not triggered by sales falling alone, if the owner kept the promises. Check the wording.Can be triggered, because the amount is still unpaid.
Why it mattersCloser to the idea that the owner stands behind honesty, not the funder profit.Closer to a traditional loan guaranty.

The first type fits the idea of a true-sale MCA: the funder takes the risk of low sales, and the owner promises to behave honestly. The second type puts the repayment risk on the owner. Which one you signed, and exactly how it is worded, can change your position a great deal. A lawyer can tell you how it reads under your state's law.

Two more things shape how heavy a guaranty is. The first is scope: does it cover only this advance, or every later renewal and side agreement too? The second is amount: is the most you could owe capped at the unpaid purchased amount, or can fees, interest and the funder's legal costs be added on top? A short guaranty can still be a large promise if the scope and the amount are open ended.

It also helps to picture the bad day before you sign. Suppose sales fall by half, and the business cannot keep up the payment. Under a performance guaranty, you would ask whether you broke any listed promise. Under a payment guaranty, you would ask how much is unpaid. The answers can be very different, and it is better to learn that now than from a demand letter.

How to find and read yours

  1. Find the signature page. Look for your name followed by "guarantor" or "owner" and a separate signature line.
  2. Read what you are promising. Is it "performance" of the merchant's obligations, "payment" of the amount, or something else? Underline the exact verbs.
  3. Find the list of triggers. If the guaranty lists acts like fraud, diversion or blocking, that points toward a performance guaranty. If it says "any amount owed," that points toward payment.
  4. Look for waivers. Many guaranties say you give up defenses, notices or the right to require the funder to go after the business first. Note each one.
  5. Check where disputes go. Look for a chosen state, a court, or an arbitration clause.
  6. Look for an end date. Some guaranties last as long as any amount is owed. Some do not say.

If you cannot tell which type you signed, that is a good question for a lawyer.

Spouses and second owners

Funders sometimes ask for more than one signature. A few things to think about:

Not legal adviceThis guide explains common ideas. It does not tell you what your guaranty means or what a court would do. Show your agreement to a lawyer licensed in your state before you sign, and again if you receive a demand.

If trouble comes

If a funder sends you a demand as a guarantor, a default notice or court papers, talk to a lawyer before you answer. Do not stop, block or reverse MCA payments on your own. Keep a copy of your signed guaranty and every notice, and write down the date you received each one. For how default is defined, see Events of default.
