# Skill: Draft Assignment and Assumption of Lease for Commercial Office Space Transfer

## 1. Subject-matter triage (only if applicable)

- Treat the lease package as the source of truth hierarchy: original lease, then amendments, riders, side letters, consent conditions, estoppel or current-state confirmation, and transaction documents.
- If the package contains multiple versions or partial excerpts, identify the governing set before drafting; do not draft from an isolated document.
- If the task arises in a closing context, align the assignment effective date with the transaction closing date and any landlord-consent timing conditions.

## 2. Failure modes the skill is correcting

- Drafts built from a single lease document ignore later amendments, riders, consent conditions, and other operative modifications.
- Financial and term provisions are copied without reconciling the current-state lease record against the operative lease stack.
- The assignment fails to state whether the assignor remains liable after transfer, or assumes a release exists when none is documented.
- Ancillary rights are treated as automatic when they may be personal, conditional, or separately consented.
- Security deposit and proration mechanics are left undefined, creating avoidable post-closing disputes.
- The companion memo omits conflicts, leaving inconsistencies embedded in the draft rather than surfaced for resolution.
- Issues are described without tying them to controlling lease language or the practical consequence of leaving them unresolved.

## 3. Legal frameworks / domain conventions that apply

- Assignment and assumption should transfer all lease rights and obligations in the amended lease package as of the effective date, subject to landlord consent.
- Landlord consent may impose conditions that must be satisfied, acknowledged, or carried forward in the draft.
- Assignor liability depends on the consent package and any express release; absent an express release, continuing liability is the default commercial assumption.
- Renewal, expansion, parking, signage, transfer, and similar ancillary rights should be addressed one by one, because their transferability often turns on lease wording or consent.
- Security deposit treatment should track the current-state lease record and specify transfer mechanics, acknowledgement, and any offset language.
- Rent and other periodic charges should be stated with the lease’s defined payment periods and prorated as of the effective date.
- For legal propositions in the memo or drafting notes, cite the controlling lease provision, amendment, consent term, or other authority relied on; do not state a conclusion without naming the supporting text or rule.

## 4. Analytical scaffolds

- Identify the complete lease instrument set, then map which document governs each contested provision.
- Reconcile current rent, term, deposits, outstanding amounts, default status, and other operational facts against the latest lease confirmation or estoppel-like record.
- Read the consent document for conditions, approvals, required joinders, and any express modification to the lease assignment standard.
- Decide whether the assignor is released, remains liable, or is only partially released, and mirror that choice consistently in both the operative draft and the memo.
- Test each ancillary right separately and label it as transferred, retained, excluded, or pending separate consent.
- Build the proration and transfer language from the operative rent definitions and the chosen effective date.
- For the memo, compare documents pairwise and then reconcile the full set, so each discrepancy is traced to its source and proposed fix.

## 5. Vertical / structural / temporal relationships (only if applicable)

- Later amendments control over inconsistent original lease language; the draft should reflect the lease as amended, not the base lease alone.
- Consent conditions may operate as closing conditions, covenant obligations, or post-closing deliveries; place each in the correct temporal bucket.
- If the transaction document references the lease assignment as a closing deliverable, the assignment should match the representations and obligations elsewhere in the deal stack.
- When the effective date, closing date, and rent-proration date differ, the draft must say which date governs which consequence.

## 6. Output structure conventions

- Produce the assignment and assumption first as the operative deliverable, with recitals identifying the governing lease documents, operative assignment language, assumption language, landlord-consent acknowledgment, and signature blocks for the required parties.
- Follow with a separate drafting issues memo that identifies each discrepancy or risk, states the governing source text, explains the practical consequence, and recommends a resolution.
- Use conventional legal drafting headings and clause structure rather than a checklist or commentary format in the assignment.
- In the memo, organize issues by topic or document conflict, not by narrative summary; each entry should be immediately actionable.
- Keep the assignment self-contained and transaction-ready; keep the memo advisory and issue-focused.
- Before finishing, verify that the primary drafted document exists and is complete, then confirm the memo is also present and non-empty.
