Organise neighbours without losing the detail

Create a simple participant table: flat, leaseholder, lease percentage, disputed years, amount paid, preferred contact and authority to act. Do not circulate private contact data more widely than necessary.

If leases or apportionments differ, calculate both the whole-building adjustment and each leaseholder's individual share. Avoid treating one flat's result as automatically transferable.

• Named participant and flat
• Copy of the relevant lease
• Apportionment percentage
• Charge years in scope
• Authority for a lead contact
• Individual payment history

An individual application keeps one leaseholder's parties, lease, payments and requested outcome together. A joint application may reduce repeated work where participants and issues genuinely align, but each applicant's authority, lease, payment history and remedy still need to be clear. Coordinated individual applications share research and controlled working documents while keeping each proceeding separate.

Before choosing, record who will be an applicant, which issues are genuinely common, where leases or payments differ, who may communicate for whom, and how deadlines, fees and decisions will be managed. Use the current form and tribunal guidance, and obtain advice if representation or authority is uncertain.

• Applicant or participant status
• Common issues
• Individual lease and payment differences
• Authority and communication scope
• Fee arrangement
• Document owner and current version

Use one lead chronology, one issue schedule and a controlled evidence index. Allocate factual witnesses by topic rather than asking everyone to repeat the same points.

A recognised tenants' association can represent shared interests and may have additional information rights, but recognition is a separate process with its own requirements. Do not delay a live deadline while assuming recognition will solve the immediate case.

Write down exactly what each participant wants the tribunal to decide, including any separate costs applications. Agree how tribunal fees and any later recovery will be divided before filing.
