An offer letter does two things at once. It is a legal document that sets out the terms of employment, and it is the first piece of professional correspondence a candidate receives from your firm after deciding they want to work there. Most offer letters are written to cover the firm legally and almost entirely ignore the second function. The result is a letter that a candidate signs with mild unease because it reads like a termination clause dressed up with a start date.
You can write a letter that protects the firm's interests and still sounds like a human wrote it to another human. Those goals are not in conflict. This post explains what needs to be in an offer letter, how to say it clearly, and how to make the candidate feel good about accepting rather than merely willing to sign.
What Every Offer Letter Must Include
Regardless of province, an employment offer letter for a law firm should address these items without ambiguity. Gaps here are what produce employment disputes later, so be complete even when complete feels tedious.
Position and reporting structure. Name the role, the location, and the person the employee will report to. If the role has a supervision component, name who oversees their work and what that oversight looks like in practice, particularly important for junior lawyers.
Start date and schedule. Give the start date and the expected hours. If the firm expects evening availability during busy periods, say so here rather than on month three of the job. If the schedule is flexible, describe what that actually means (core hours, expected weekly hours, remote work if applicable).
Compensation. State the base salary as an annual figure and a per-period amount, the pay frequency, and any bonus or commission structure. If there is a bonus, describe what triggers it and how it is calculated. "Discretionary" is not a sufficient description if you want the candidate to make an informed decision. Be straightforward about what they can realistically expect. Refer to what fair pay for legal staff looks like for context on market positioning.
Benefits. List what is covered, when coverage starts, and who pays for what. Waiting periods matter because a candidate making a decision about health coverage needs to know if there is a 90-day gap they need to plan for.
Vacation and leave. State the vacation entitlement in days per year, not just "as per provincial standards," which tells the candidate nothing useful. If your firm provides more than the statutory minimum, say so plainly, because it is a genuine advantage.
Note. Offer letters for lawyers who are newly called, articling students, or mid-hire associates should also address any law society supervision obligations if applicable. If your firm is providing a principal for articling purposes, name the principal in the letter. If there are law society reporting requirements tied to the role, a brief reference to them prevents surprises later.
What candidates notice most in an offer letter
Termination Clauses: Write Them So They Hold
This is the part of an offer letter that makes most non-employment-lawyers uncomfortable to write, and it deserves real attention. A termination clause that was not drafted carefully, or was copy-pasted from a template that is now out of date with current case law, may not be enforceable, which means the firm could owe the employee more than it intended at the time of separation.
Have an employment lawyer review your standard termination clause at least once, and update it when there are significant changes in provincial employment standards legislation or relevant court decisions. The clause should address notice periods for termination without cause, reference provincial minimums, and not attempt to contract out of statutory entitlements in ways the courts have consistently refused to enforce. This is an area where good advice upfront costs far less than a dispute later.
The probationary period, if you include one, should also be clearly described: the length, what the employee's rights are during that period, and what happens at the end. Vague probationary language is regularly used as justification for summary dismissal in ways that then get litigated. Be precise.
Making the Letter Sound Like a Welcome
After all the necessary legal provisions, there is room for one or two genuine paragraphs that express why you hired this person. Not marketing language. Not "we look forward to your contribution to our dynamic team." Something specific: what impressed you about them, what role you see them growing into, and what you are looking forward to doing together.
A candidate who receives an offer letter with a warm, specific closing paragraph feels different about accepting than a candidate who receives a dense legal document. The feeling translates into how they talk about your firm before they even start, and it sets a tone for the relationship that either helps or hinders the first 90 days. The onboarding plan that follows matters, but the letter is the candidate's first look at what kind of firm they are joining.
Tip. Before sending, read the letter aloud. If any sentence sounds like a form or sounds unlike something a person would say, rewrite it. The test is not whether it is legally adequate, it is whether a candidate will read it and feel good about their decision. Both things should be true of the same letter.
The Offer Expiry and What Happens After
Give the candidate a reasonable time to accept: typically five to ten business days, depending on whether they have another offer to consider or family circumstances that require thought. Do not pressure people into accepting on the spot. A candidate who accepts under pressure and then backs out, or accepts and immediately starts looking again, is worse than a candidate who takes a week to decide and then commits fully.
After acceptance, confirm receipt in writing and give the candidate a clear next-steps note: what documents you need from them, who to contact with questions, what to expect on their first day, and a name and phone number they can actually reach. The gap between signing and starting is often where candidates develop second thoughts, especially if they hear nothing from the firm after the offer is signed. A brief, human check-in the week before their start date costs nothing and prevents a lot of pre-start anxiety.
Keeping the Process Consistent
If you hire more than occasionally, standardize the offer letter template so that the mandatory provisions are always included and always current, but leave space for the role-specific and personal sections to be written fresh each time. A partially templated letter is the right balance: consistent on the terms that must be consistent, specific on the things that should be specific.
The same consistency that makes a good offer letter makes a good firm to work for. Candidates who feel the process was clear and fair from the start are more likely to refer others when they are eventually hiring their own staff. See the associate hiring guide, the post on hiring your first legal assistant, and the people and hiring category for the full picture of building a team that stays.
