Electronic working-time record for law firms
Short answer
A law firm can comply with the electronic working-time record by combining a QR code on the premises with location-based recording for those who work outside. The law asks for recording each person's start and end times; it does not ask for a wall-mounted time clock.
How work is done at a law firm
A law firm employs lawyers, junior associates, secretaries and process servers, with an office, courts and hearings with unpredictable schedules. That brings three challenges for measuring working time:
- Junior associates and lawyers stretch their workdays because of filing deadlines.
- Process servers spend the day at government offices.
- It is assumed that no one clocks in.
What the law asks of law firms
Since the 2026 reform, the Federal Labor Law requires recording electronically the start and end time of each worker's workday (article 132, section XXXIV). Failing to do so is fined 250 to 5,000 UMA. The STPS will define who it applies to and what exceptions there will be. The details are in the reform guide.
Work peaks. Overtime has a weekly cap: 9 hours at double time in 2027, with a maximum of 4 per day on no more than 4 days, and never more than 12 total hours in a day.
Work outside the premises. The time a person is at the company's disposal is working time, even if they are not at your facilities.
Work from home. Someone who works remotely also has working hours. The law does not exclude them from the record.
How to record working time at a law firm
- Register the location, your team and their shifts.
- Those who work on site scan the QR code.
- Those who work offsite clock in from their phone, with the location confirmed at that moment.
- They all appear in the same report, with the place or mode of each record.
Example. A firm that advises companies on the working-time record should be the first to keep its own.
Calculate your overtime
How to do the math by hand
Take a salary of $400 per day on a day shift. The ordinary hour is worth 400 ÷ 8 = $50. In 2027, with 11 overtime hours in the week, the first 9 are paid at double time (9 × $100 = $900) and the remaining 2 at triple time (2 × $150 = $300). Total: $1,200.
Common mistakes at a law firm
- Keeping attendance from memory or in a notebook.
- Recording the clock-in and forgetting the clock-out.
- Covering peaks only with overtime, until exceeding the weekly cap.
- Asking staff who work offsite to stop by the office just to clock in.
- Assuming that someone who works from home has no working hours.
What to check every day and every week
Every day.
- Who did not record their clock-in or clock-out.
- Records made in unexpected places.
- Departures later than planned.
Every week.
- Each person's overtime against the weekly cap.
- Days when someone came close to 12 hours.
- Rest days that were actually taken.
How much an overtime hour costs: example in pesos
Suppose a daily wage of $600 on a day shift. The ordinary hourly rate is $75. One overtime hour at double time costs $150 and one at triple time, $225. If a person works 9 overtime hours in a week in 2027, that is $1,350 extra.
It is an example to show the calculation, not a reference wage for the sector.

Frequently asked questions
Does a law firm need to buy a time clock?
No. The law requires an electronic record of working time, not a device. An app on a phone complies.
What options are there for recording working time?
An app on each person's phone, a shared tablet or a clock connected to a system. All three comply if they generate an electronic record per person, with a start and an end time.
Can I ask for more overtime in peak season?
The weekly cap is not extended for the season. It helps to plan relief staff.
Is staff tracked during the day?
No. The location is used only at the moment of recording.
Is the maximum workday per day or per week?
There are two limits: a daily one, which did not change, and a weekly one, which drops from 48 to 40 hours between 2027 and 2030.
