Handover at the end of an assignment: securing knowledge, closing access, onboarding the successor

Short answer: A good handover at the end of an interim assignment secures three things: knowledge of open matters, deadlines and decisions, onboarding of the successor, and closure of all access rights. This interim handover checklist gives every item an owner. In staff leasing the company runs the handover; in freelancing it is part of the mandate.

This guide is for general counsel, heads of legal and heads of compliance in Switzerland and Germany whose interim professional or interim manager leaves in a few weeks. It shows when the checklist helps, what belongs in a handover file and which mistakes cost knowledge.

When the interim handover checklist helps

The checklist helps whenever an interim professional leaves and someone else carries on their work. Typical situations are:

• Return from parental or sick leave: the postholder takes over again and needs a clear status of every matter.
• A permanent hire starts: a newly hired person takes over the role the interim professional has bridged.
• End of a project: a project such as a remediation or a contract review is complete and the internal team takes over day-to-day work.
• Change of interim professional: another professional continues the assignment, for example because the focus has shifted.
• Early end: the assignment ends sooner than planned. This is exactly when a short, structured handover matters most.

Whether an assignment is extended or ended, and which notice periods apply, is covered in the guide Extending, ending or handing over an interim assignment. This guide picks up from there: the handover itself.

The handover in five steps

A handover works when it starts as a plan, not on the last day. This sequence works well:

1. Fix the end date and the successor: who takes over which tasks from which date? If there is no successor, decide which tasks pause and who watches the deadlines.
2. Build the handover file: the interim professional documents open matters, deadlines, decisions, contacts and filing locations in the company's systems.
3. Use an overlap: the interim professional and the successor work in parallel for a while. The successor takes over simple matters first, then the critical ones.
4. Inform stakeholders: business units, management, law firms and authorities learn who is responsible from when.
5. Close out: hold an exit meeting, close access, collect devices and documents, file the confirmations.

How long the overlap lasts depends on the role and its complexity. In the case study Senior legal counsel as parental leave cover, the nine-month assignment included a one-month overlap.

The checklist: item, why, who

The checklist covers the three aims of a handover: securing knowledge, onboarding the successor and closing access. Every item has an owner.

Confidentiality after the assignment is covered in detail in the guide Confidentiality and access rights for interim legal and compliance staff.

What belongs in a handover file

A handover file is a short document the successor can read in an hour, with links to where things are filed. These sections work well:

• Brief and status: what was the brief, what is done, what is open?
• Matters: a list with status, next step, deadline and filing location.
• Decisions: the key decisions of recent months and the reasons for them.
• Processes and templates: which workflows the professional introduced or changed, and where the templates are.
• Relationships: contacts in business units, law firms and authorities, with current topics.
• Risks: what the successor needs to keep an eye on.

Start the file early. If it is set up during onboarding and kept up to date, little extra work remains at the end. The onboarding checklist for interim professionals shows how to set up the start accordingly.

Who runs the handover: staff leasing and freelancing

In staff leasing, the company runs the handover, because it holds the right to give professional instructions and the professional is integrated into its organisation. You can therefore decide what is documented by when. In freelancing, the professional delivers on their own responsibility within the agreed mandate. Agree the handover as a deliverable in the mandate from the outset, with scope and date.

Alpinum Solutions provides interim legal and compliance professionals through staff leasing and freelancing, part-time or full-time, and plans the end of each assignment with the company and the professional. If you need another professional without a gap, selected profiles are usually available within 48 hours; the start date is agreed between the company and Alpinum. If the professional should stay, a move into your team (temp-to-perm) is possible; the terms are agreed in advance.

Common handover mistakes

• Starting too late: if the handover is planned in the final week, there is no time for an overlap or follow-up questions.
• Knowledge in heads, not systems: decisions and their reasons exist only in the professional's emails or local files.
• No named successor: nobody feels responsible for open matters and deadlines pass unnoticed.
• Forgotten access: accounts in specialist systems, data rooms or authority portals stay open because they are not managed by central IT.
• Powers of attorney not revoked: individual powers and signing rights remain in place after the assignment.
• No exit meeting: the professional's view of risks and recommendations is lost.

Frequently asked questions about interim assignment handovers

When should the handover start?

Plan the handover as soon as the end date is fixed and start the handover file a few weeks before the last working day. That leaves time for an overlap with the successor, for questions and for closing access. If an assignment ends early, a shorter version of the checklist is often enough, as long as deadlines, open matters and access rights are covered.

What goes into a handover record?

A handover record states which matters, documents, devices and access rights were handed over and to whom. It lists open matters with status and deadline, confirms the return of devices and documents and records that accounts have been blocked. Both sides sign it and the company files it.

How long should the overlap with the successor be?

It depends on the role, its complexity and the number of critical matters. Cover for a leadership role justifies a longer overlap than a defined project. In the case study on parental leave cover for a senior legal counsel, the nine-month assignment included a one-month overlap in which both people worked in parallel.

Who is responsible for closing access?

The company is, because it granted the access. Line management tells IT and information security the end date early; IT blocks the user account, email, VPN and specialist systems no later than the last working day. Accounts in external portals, data rooms or authority portals belong on a separate list, because central IT often does not know about them.

Can the interim professional stay available for questions after the assignment?

Yes, if it is agreed in advance. A short window for questions after the end date is often enough. In staff leasing, agree scope and billing with the provider; in freelancing, agree it directly in the mandate. A complete handover file that makes follow-up questions unnecessary is the better solution.
