What should a succession timeline look like?

A good succession timeline runs in phases rather than to a single date: deciding, developing the successor, preparing the rooms they will lead, the handover itself, and the first years after it. Each phase has work on three tracks at once: ownership and structure, leadership, and the family. The durations vary by family, but the order rarely should, and each phase needs an owner and a review date.

Most families who say they have a succession timeline have a date. Sometimes it is a birthday, sometimes a retirement year, sometimes “in about five years”. A date is useful, but it is not a timeline. A timeline says what has to be true at each stage, who makes it true, and how the family will know.

Why one track is not enough

Succession is usually planned on one track: the structure. Shares, trusts, wills, tax, governance. That work belongs with lawyers, accountants and the family’s advisors, and it often has its own long lead times.

Two other tracks move at the same time, and they are planned far less often.

The leadership track. Whether the successor will actually be followed by the board, the senior team and outside partners when the title moves.
The family track. Whether siblings, the wider family and the parent’s own new role have been talked through and agreed.

A timeline that only covers the structure can be complete on paper and still fail in the room. The phases below put all three tracks side by side.

Phase 1: Deciding

Often five years or more before the handover, though many families start later.

This is the phase in which the family settles the questions everything else depends on: whether the business stays in the family, whether there is a successor who genuinely wants the role, and roughly when the parent intends to step back.

Ownership and structure. A first conversation with the family’s advisors about the options and their lead times. No decisions need to be final yet.
Leadership. The successor makes a free decision to lead. Pressure at this point tends to cost more later.
Family. The parent tells the family what they are considering, before rumours do it for them.

The phase ends when there is a named successor, a target window for the handover and a shared understanding of what the parent’s role will become.

Phase 2: Developing

Roughly two to five years out, depending on the successor’s starting point.

Here the successor builds experience and a track record: a role with genuine responsibility, measurable results, perhaps time outside the company first. The detail of this phase belongs in a successor development plan, which sets out the role, the baseline, the development areas and the milestones.

Ownership and structure. The main legal and tax work is designed and, where it takes time, started.
Leadership. The successor runs something that is clearly theirs. The parent stops overturning their decisions in public.
Family. Rules for family employment, ownership and communication are discussed, and written down if the family wants them to last.

Phase 3: Preparing the rooms

Usually the last twelve to twenty-four months.

This phase is the one most often skipped. The successor may know the business well, but the moments that grant or withhold authority are specific: the board meeting, the senior team, the bank, the key customers, the family table. They need deliberate preparation, while the parent is still there to support rather than rescue.

Ownership and structure. Documents are finalised so the legal transfer can follow the leadership handover, not lag years behind it.
Leadership. Board exposure, introductions to key relationships, one-to-ones with senior executives, rehearsal before high-stakes events.
Family. A family meeting about the handover, and agreement on how it will be announced.

How long this preparation takes, and why it runs on a different clock from experience, is covered in how long it takes to prepare a successor.

Phase 4: The handover

A defined date, with decisions moving in stages over the months around it.

A handover is not a single day. The title may move on one date, but decisions are best moved in a sequence that everyone knows: hiring below the executive team first, then budgets, then the external relationships, then the largest calls.

Ownership and structure. Whatever transfers at this point transfers as planned, with the family’s advisors involved.
Leadership. The successor addresses the company in their own name. The parent’s new role starts.
Family. The founder and successor agree, in writing, what changes and when, and how they will disagree from now on.

Choosing the moment itself is a judgement of its own, discussed in when is the right time to hand over.

Phase 5: After the handover

The first one to two years.

Families often stop planning at the handover. The first year is when the arrangement is tested: the first bad quarter, the first senior departure, the first decision the parent would have made differently.

Ownership and structure. A review of whether the governance is working as designed.
Leadership. The successor builds their own team and makes their first large decision without the parent’s visible approval.
Family. A planned check-in, perhaps after six and twelve months, to revisit the agreements while they can still be adjusted calmly.

How to build your own timeline

A simple method works for most families.

Start from a target window, not a single date. “Between spring and autumn of a given year” is easier to keep than a birthday.
Work backwards. For each phase, write down what must be true at the end of it, on all three tracks.
Name an owner for each item. The parent, the successor, a named advisor. Items with no owner tend not to happen.
Use conditions as well as dates. “The successor presents their own results to the board for two consecutive quarters” is a better milestone than a month on a calendar.
Set review points. Once or twice a year, founder and successor look at the timeline together and adjust it openly.
Plan for the unplanned. Illness, a sudden offer for the business or a family event can compress years into weeks. Know who would lead tomorrow if they had to.

What makes timelines slip?

Most timelines slip for ordinary reasons. The business is doing well and there is one more project. Nobody defined what “ready” means, so it never quite arrives. The structure track moves ahead and everyone assumes the rest will follow.

The remedy is not a stricter date. It is clearer milestones, honest reviews and a parent willing to say out loud when they are the reason for the delay.

In short

A succession timeline is a sequence of phases, not a single date.
Each phase has work on three tracks: ownership and structure, leadership, and the family.
Durations vary by family; treat any ranges as a starting point for judgement, not a rule.
The phase most often skipped is preparing the successor for the specific rooms they will lead.
Build the timeline backwards from a target window, with owners, conditions and regular reviews.

Phase 3 is the part of the timeline the Second Chair™ method is built for.
