Lease Amendments

Modify active leases through formal amendments (avenants). Amendments create a legal record of changes made to the original lease terms.

When to use amendments

Amendments are required when changing:

• Rent amount (outside annual revision)
• Lease duration
• Adding or removing tenants
• Changing charges or payment terms
• Adding special conditions

Note: Annual rent revisions using the IRL index are handled automatically and do not require an amendment. See Leases API for rent revision endpoints.

Create an amendment

Code
 
curl -X POST https://api.faireplace.com/api/leases/{lease_id}/amendments \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Avenant n°1 - Modification du loyer",
    "effective_date": "2026-07-01",
    "changes": {
      "rent_amount": 980.00,
      "special_conditions": "Loyer revise suite a travaux d amelioration"
    },
    "reason": "Travaux d amelioration realises par le proprietaire"
  }'

Code
 
{
  "id": "amend-aabb1122-3344-5566-7788-99aabbccddee",
  "lease_id": "lease-4d5e6f78-90ab-cdef-1234-567890abcdef",
  "title": "Avenant n°1 - Modification du loyer",
  "status": "Draft",
  "effective_date": "2026-07-01",
  "changes": {
    "rent_amount": {
      "previous": 950.00,
      "new": 980.00
    }
  },
  "created_at": "2026-02-20T10:00:00Z"
}

List amendments

Code
 
curl https://api.faireplace.com/api/leases/{lease_id}/amendments \
  -H "Authorization: Bearer $TOKEN"

Generate amendment PDF

Code
 
curl -X POST https://api.faireplace.com/api/leases/{lease_id}/amendments/{amendment_id}/pdf \
  -H "Authorization: Bearer $TOKEN"

The amendment PDF includes:

• Reference to the original lease
• Summary of changes (previous value → new value)
• Effective date
• Signature pages for all parties

Sign an amendment

Amendment signing follows the same process as lease signing:

Code
 
curl -X POST https://api.faireplace.com/api/leases/{lease_id}/amendments/{amendment_id}/signature/initiate \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "pdf_id": "<amendment_pdf_uuid>",
    "signers": [
      {"type": "Proprietaire", "name": "Jean Dupont", "email": "[email protected]", "phone": "+33612345678"},
      {"type": "Locataire", "name": "Marie Martin", "email": "[email protected]", "phone": "+33698765432"}
    ]
  }'

Amendment signatures consume 1 signature credit, the same as lease signatures.

Apply the amendment

Once signed, the amendment changes are applied to the lease:

Code
 
curl -X POST https://api.faireplace.com/api/leases/{lease_id}/amendments/{amendment_id}/apply \
  -H "Authorization: Bearer $TOKEN"

The lease is updated with the new values as of the effective_date.
