Downloading shares your name, firm, role, and email with CaseMark. That introduction is what keeps every skill here free.

What this skill does

Drafts a secured commercial promissory note: rate and day count, payment schedule and application of payments, late charges and default rate, a usury savings clause, the collateral grant, defaults and remedies. The draft goes to your attorney to finish.

What it does

  • Collects the intake fields and flags anything unresolved before drafting
  • Follows a 15-section outline from promise to pay through signatures
  • Adds optional clauses only when the deal needs them — balloon, interest-only, cross-default, lockbox
  • Runs a review checklist for usury limits, collateral description, cure periods and signing authority

When to use it

  • Closing a business-purpose loan
  • Replacing a note form
  • Papering a loan with unusual payment terms

What to have ready

  • Borrower and lender legal names and entity details
  • Principal, rate, day count, payment schedule and maturity
  • Late fee, default rate and prepayment terms
  • Collateral description and related security documents

How to use it

  1. Download it with the button above. You'll sign in with a work email — that's how the creator knows who is using their skill.
  2. Copy the install prompt from the "Run it in Claude" box, and paste it into Claude along with the file. Claude installs the skill, fills in your firm's details where the file has [BRACKETED] placeholders, and runs a quick test with you.
  3. Then just ask in plain English. Claude picks the skill up on its own when a request matches it. Anything it still needs, it asks you for — it won't invent a number.

"Draft a 12-month interest-only secured note for $[AMOUNT] at [RATE]% to [BORROWER LLC], secured by a deed of trust on [PROPERTY ADDRESS], governed by [STATE] law."

What you get back

A draft secured promissory note with a collateral schedule and a completed review checklist.

Good to know

  • Output quality tracks input quality. A missing figure is flagged as missing — it is never estimated to fill a gap.
  • Every draft is a starting point for your own review, not a finished decision.
  • Runs anywhere Claude does: the Claude app, Claude Desktop, or Claude Code.
  • Draft for attorney review only. Interest, default rate and fees must be checked against the governing state's usury and fee limits. Real estate collateral also needs a mortgage or deed of trust. Built for business-purpose loans; consumer-purpose loans need counsel.

Legal disclaimer

This skill drafts; it does not decide. Its output is not legal, tax, accounting, appraisal, or investment advice, and using it creates no attorney-client, fiduciary, or advisory relationship. Nothing it produces is a commitment to lend or an offer to sell a security.

Changes made by LenderSkills: front matter rewritten to name/description/license/metadata (upstream description kept verbatim); renamed from "secured-promissory-note" to "secured-promissory-note-drafter" so the catalog name reads as a lender task; added a LenderSkills draft-only / business-purpose note under the title; rewrote the "Consumer loans" pitfall, which implied a loan to any individual borrower needs consumer disclosures (the test is loan purpose, and a consumer-purpose loan needs counsel, not a template). A legal disclaimer will be appended by LenderSkills at the end of the file. Otherwise the author's content is unmodified.

Secured Promissory Note

Draft an enforceable secured promissory note for a commercial loan with collateral-backed repayment.

LenderSkills note: Everything this skill produces is a draft for review and completion by the lender's attorney, not a finished document and not legal advice. It is written for business-purpose commercial loans. If the borrower is an individual borrowing for personal, family or household purposes, or the property is the borrower's home, stop and send the file to counsel: consumer-lending rules apply and this template does not address them.

Quick Start

Gather before drafting:

  1. Parties — borrower and lender legal names, entity types, states, addresses, authorized signatories.
  2. Deal terms — principal, interest structure (fixed/variable, index, margin, floor/cap), day-count convention, payment schedule, maturity, prepayment, fees, default rate.
  3. Collateral — description with sufficient detail for UCC Article 9; filing jurisdictions (debtor location, fixture/real property).
  4. Governing law — state, venue, dispute resolution preference.
  5. Related documents — security agreement, guaranty, subordination/intercreditor, board/manager approvals.

Workflow

  1. Collect intake fields; flag unresolved items before drafting.
