Lease Abstraction

Check amendment order before CAM review

Map which lease terms appear current before CAM review.

By Angel Campa, FounderUpdated July 15, 2026

I work as a principal engineer. I built the engine behind these audits. Each finding points to the lease clause and the bill line. Your team reviews and signs first.

Check amendment order before CAM review

Check amendment order for each CAM clause family.

Do not pick one lease-wide winner. A later file may change one term. Other terms may stay.

This guide proposes a clause graph. Each edge needs clear change words and source pages.

List every signed file

Build the file chain before reading clause changes.

List these document types:

  • Base lease
  • Amendment
  • Addendum
  • Rider
  • Exhibit
  • Assignment
  • Restatement
  • Side letter

Record five facts for each file:

Fact What to record
Document type Name used in the file
Signed date Date beside the signatures
Effective date Date the terms take effect
Parties Names shown in the file
Prior file link File named in the new text

Leasecake calls for all exhibits and addenda during file prep. Use that as a full-file check.

A missing signed file is a stop. Use the readiness score before clause work begins.

See the firm page when naming the file owner.

Split clause families

Build one path for each term. Do not use one lease-wide label.

Track these CAM families:

  • Expense meaning
  • Expense exclusions
  • CAM cap
  • Management fee
  • Gross-up right
  • Pro rata share
  • Review period
  • Audit rights
  • Notice method
  • Notice address

Accruent lists clauses and dates as field types. That does not create a legal order rule.

Use the minimum field guide for each node.

Read the words that connect old and new text.

Add one graph edge for each clear act:

Act Plain meaning
Adds Creates a new term
Deletes Removes stated text
Replaces Swaps old text for new text
Qualifies Narrows or limits old text

Do not infer a full change from a later date. Record the exact words and source page.

Ballard Spahr says the lease controls when a dispute needs review. Keep the full chain with each abstracted term.

Build the clause graph

Use one row for each graph edge.

Field What it shows
Clause family Term under review
Earlier node Older file and page
Later node Newer file and page
Link words Adds, deletes, replaces, or limits
Change scope Whole term or one part
Open issue Fact that still needs review
Reviewer Person who made the firm call

The graph shows an apparent path. It does not give legal advice.

Start with these five family paths:

Clause family Add an edge when text If text is unclear
CAM cap Changes rate, base, or carry rule Hold for review
Exclusions Adds or deletes a named cost Keep both nodes open
Pro rata share Replaces the percent or method Check both sources
Dates Changes an event or notice date Hold the date conflict
Audit rights Changes window, records, or notice Send meaning to counsel

Use the lease abstraction growth pillar when adding this check.

Send path conflicts to the CAM clause QA queue.

Mark five stop signs

Stop the clause path when proof is weak.

  1. A file lacks a signed page.
  2. A page is missing.
  3. An attachment has no clear link.
  4. Two effective dates conflict.
  5. The change words remain unclear.

Do not fill the path from memory. Name the missing proof and owner.

Send unclear legal effect to counsel. Keep counsel's advice outside the abstract field.

Walk one cap example

This example is fictional. It is not legal advice or a client result.

The base lease sets a five percent CAM cap. It also lists three expense exclusions.

Amendment 1 replaces five percent with three percent. It names only the cap rate.

Build two clause paths:

Clause family Base node New node Apparent result
CAM cap rate Five percent Three percent Rate appears changed
Exclusions Three exclusions No new text Base list stays open

Do not say Amendment 1 replaced the full CAM clause. Its words changed the rate only.

The exclusions need their own path. A later date alone does not remove them.

If Amendment 1 had no signature page, stop both paths. Ask for the signed file.

Keep a reviewer log

Record the review result. Name who accepted, held, or sent the edge.

Log field Example entry
Clause family CAM cap rate
Decision Apparent change
Source pages Lease 22 and Amendment 1 page 3
Link words Replaces stated rate
Open issue Expense base not changed
Reviewer Named firm reviewer
Next action Send unclear effect to counsel

Keep the old and new values. Do not erase the audit trail.

Browse the lease abstraction hub for source controls.

Use the service line guide before selling this check.

Where CAMAudit fits

Return to signed Amendment 1. It changes the cap rate only.

The lease abstraction firm keeps exclusions on its own path.

After review, CAMAudit reads the signed lease and amendment. It also reads the CAM statement.

It can apply fixed cap math from the reviewed term. It may flag a cited review item.

Your team reviews and signs the branded CAM audit.

A dispute letter draft may follow that reviewed item.

It is a draft for your review. It is not legal advice.

Have counsel review before sending.
