A promissory note is a written promise to pay a specific amount on demand or at a definite time. It's a negotiable instrument governed by UCC Article 3 and state contract law.
| Type | Payment Terms | Example |
|---|---|---|
| Demand Note | Payable whenever lender demands | "Payable on demand" |
| Term Note | Due on specific date | "Due August 1, 2025" |
| Installment Note | Monthly/periodic payments | "$500/month for 36 months" |
| Balloon Note | Small periodic payments + large final payment | "$200/month, $10,000 due on maturity" |
| Secured Note | Backed by collateral (security agreement) | "Secured by lien on 2020 Toyota Camry" |
| Unsecured Note | No collateral | "This is an unsecured obligation" |
Read the note carefully. Default typically includes:
| Type of Default | Description |
|---|---|
| Payment default | Missed installment or failure to pay at maturity |
| Non-monetary default | Breach of covenant (e.g., failure to maintain insurance on collateral) |
| Insecurity default | Lender deems itself insecure (rare; requires good faith belief of impairment) |
| Cross-default | Default on another obligation triggers default on this note |
| Bankruptcy filing | Borrower files for bankruptcy (automatic stay complicates collection) |
Many notes include a cure period:
"Borrower shall have 10 days after written notice of default to cure the default before Lender may accelerate the note."
If your note has a cure period:
Before demanding payment, calculate the exact amount owed:
Acceleration means declaring the entire unpaid balance immediately due, rather than waiting for future installments to become due.
Acceleration clause example:
"Upon default, Lender may declare the entire unpaid principal and accrued interest immediately due and payable."
Why accelerate?
These are often combined in one letter:
If the note is secured by collateral (real estate, vehicle, equipment, inventory), you have additional remedies and considerations.
| Collateral Type | Security Document | Enforcement Remedy |
|---|---|---|
| Real estate | Mortgage or Deed of Trust | Foreclosure (judicial or non-judicial depending on state) |
| Vehicles | UCC-1 on title; security agreement | Repossession |
| Equipment/inventory | UCC-1 financing statement; security agreement | UCC Article 9 sale or repossession |
| Accounts receivable | Security agreement; UCC-1 | Direct collection from account debtors |
Your demand letter should reference the security:
Foreclosure (secured by real estate):
Repossession (vehicles/equipment):
Sue on the note (ignore collateral):
Personal loans between friends, family members, and acquaintances are the most common, and most emotionally difficult, promissory note disputes. I handle these cases regularly and have developed a strategic approach that balances legal enforcement with relationship preservation where possible.
Many personal loans lack formal documentation. Here's what I look for to build your case:
| Defense | Your Rebuttal Strategy |
|---|---|
| "It was a gift" | Show repayment discussions, partial payments, or written acknowledgment |
| "I already paid you back" | Demand proof of payment; bank records show no matching deposits |
| "The terms were different" | Your written note controls; parol evidence rule limits oral modifications |
| "You said I could pay whenever" | Demand note allows you to demand at any time; statute of limitations runs from demand |
| "I can't afford it" | Inability to pay is not a defense to the debt; negotiate payment plan |
If the borrower truly cannot or will not pay, the promissory note may qualify for a bad debt deduction under Internal Revenue Code §166. This is where demand letters become tax documentation, and it's a strategy I coordinate with my clients' CPAs regularly.
| Requirement | What the IRS Wants to See |
|---|---|
| Bona fide debt | A genuine debtor-creditor relationship (not a gift disguised as a loan) |
| Debt became worthless | Evidence that borrower can't pay and further collection is futile |
| Collection efforts | Demand letters, phone records, payment negotiations, proof you tried to collect |
| Debtor's financial condition | Insolvency evidence, bankruptcy filing, no attachable assets |
| Proper classification | Business debt (ordinary loss) vs. nonbusiness debt (short-term capital loss) |
The IRS specifically looks for evidence of collection efforts. My demand letter packages for tax documentation purposes include:
I work directly with your CPA or tax preparer to ensure the documentation meets IRS requirements:
| Service | Fee | What's Included |
|---|---|---|
| Single demand letter | $1,200 | Formal collection demand + certified mail |
| IRC §166 documentation series | $1,200-750 | 2-3 demand letters + collection timeline + CPA package |
| Pro se filing setup | $1,250 | Court complaint + filing instructions (strengthens worthlessness claim) |
| Full representation | $300/hr | Litigation, judgment, post-judgment enforcement |
I handle promissory note collection from first demand through judgment enforcement. My practice focuses on the cases that fall between "too small for a big firm" and "too complex for small claims", typically $10,000 to $250,000 in dispute.
Want me to write it and send it?
I take a dispute like the one on this page and write the demand myself, on my letterhead, then handle delivery and read the response you get back.
