What Is a Personal Guarantee?
A personal guarantee is a promise by an individual — often a small-business owner or tenant — to personally cover an obligation if the business or primary party doesn't pay. It reaches past the LLC, corporation, or lease deposit that would otherwise limit exposure, putting personal assets (savings, sometimes a home) on the line.
Why it matters
Forming an LLC or signing a lease with a security deposit is supposed to draw a line around your risk. A personal guarantee erases that line for the specific obligation it covers — which is exactly why landlords, lenders, and vendors ask small-business owners for one: it converts a business risk they'd otherwise absorb into a personal risk you absorb instead. The two-page guarantee attached to a lease or loan is often the highest-stakes page in the entire document.
What to watch for
- Unlimited guarantees: covering any amount owed, indefinitely, rather than a capped sum or a limited period.
- "Joint and several" guarantors: if more than one person guarantees, each can be pursued for the entire amount, not just their share (see joint and several liability).
- Guarantees that outlast the deal: continuing to cover renewals or amendments you never separately agreed to.
- No release mechanism: no path to end the guarantee even after the underlying obligation is satisfied or the business relationship ends.
A realistic example
A small-business owner signs a five-year commercial lease with an unlimited personal guarantee to get better terms. Three years in, the business struggles and defaults. The landlord doesn't just claim the security deposit — the guarantee lets them pursue the owner's personal savings for the remaining two years of rent, well beyond what the deposit or the LLC structure would have covered.
What to ask for
- A cap: limit the guarantee to a fixed dollar amount or a limited time (e.g., the first 12–24 months of a lease), not the full remaining term.
- A decreasing guarantee: many landlords will accept a guarantee that shrinks each year as a track record builds.
- A clear release condition: the guarantee ends on a stated date or event, not indefinitely.
