Best Time to Post on Instagram for Law firms (Your clients, Not the Chart)
Quick answer: the best time to post on Instagram for law firms is the hour your own followers are most active, which Instagram Insights shows under your audience. Published charts average other accounts. Most legal Instagram is optional; the people who matter may be on LinkedIn during the working day. Check your own numbers, or use a scheduler that reads them.

Whose clock are law firms on?
Commercial, employment and property clients are at their desks. Family, wills and conveyancing clients are often on Facebook and Instagram after work. The firm that treats those as one audience picks an hour that serves nobody.
Instagram is optional for a lot of firms. If the feed is stock gavels, the hour will not save it. If the partner has a point of view and a younger client base, Insights for that profile is the chart. What practitioners generally see is a working-day peak on LinkedIn and a later peak on Instagram. Convention, not a rule.
What Insights will show you
On a professional account, Insights under Your audience has Most active times by hour and day. That is your patients, clients or guests - not a national average. Instagram moves the menu; start at your profile and look for Insights or Professional dashboard.
Write down the top slot for the days you actually post. Check it again in a couple of months. It drifts.
What if the account is new?
A firm page that posts the office drinks twice a year has no timing data. Start with the partner's profile, one general question a week, and a slot they will actually approve. Insights can wait.
Stories, feed and Reels
Carousels of a change in the law belong on the feed and on LinkedIn. Stories are for the human bit - the person, not the advice. Reels of a partner talking to camera travel further than the hour they went out.
Never time-optimise a post that answers a specific person. Generalise first. Then pick the slot.
How does Magic Marketer® pick the time?
From your own Instagram history: when your followers have engaged with your posts before. It needs enough posts to see a pattern, so on a brand-new account it uses a sensible default until your numbers arrive, then switches.
On the review screen you can publish now, pick a time, or choose "schedule for best performance". Most people choose the third and stop thinking about it, which is the point.
The hour is not the lever
The post that gets shared by accountants is the plain-English change in the law, not the 8am publish. The hour is a setting. The question, in general, is the work.
If the problem is the hour, the feature fixes it. If the problem is that there are no posts to schedule for law firms, Magic Marketer® makes those too: one source becomes a set of posts in your voice, and each one goes out at the best time for your account.

Questions
When your own Instagram followers are most active, which Insights shows under Your audience. Desk-hours clients and after-work clients are not the same clock. A published chart is someone else's audience.
