By engaging us, you will quickly regain control over your international file. Already, more than 24,000 lawyers benefit from our services.

The IJI is a small-scale firm. That is our strength: you will always have personal contact with one of our legal counsels and lines of communication are short.

We have a global network of legal experts from both academia and practice. This network can be called upon when your case requires it.

Up-to-date Expertise

We have strong ties with legal experts from practice (the judiciary and the legal profession) and academia, and we actively participate in the academic debate. As a result, we are well-informed about the latest developments in our field of law.

Independent Advice

Our reports can be used to support a court judgment, as the basis for a notarial deed or the substantiation of a procedural document.

What our Clients Say About Us

Lawyer Tim de Greve, partner at Stibbe.

I regularly engage the IJI in cases where PIL aspects play a role. The institute has existed for over 100 years and can therefore boast a long history and experience. There are prominent people associated with it. Not least Mr Strikwerda. They support you from the outset, immediately understand the question you are faced with and suggest possible solutions. They have the right connections at home and abroad to answer questions within a reasonable timeframe. Apart from that, it is very pleasant to work with the people of the IJI.

Lawyer Leushuis, Leushuis Advocaten

As a lawyer, I have a normal legal practice and I am rarely confronted with international aspects. It is not feasible to have to find out the PIL for international files. In this day and age you really need a PIL expert for that. I really think the quality of IJI reports is worth a 10. I receive very thorough reports that I am very happy with and so are the clients. The speed of the service is also very good and is actually even faster than I expected. It was also nice that the contact with the IJI employees is very pleasant. I am glad that the institute exists and that the legal profession can be helpful.

Attorney Ria van Seventer, Meesters aan de Maas Advocaten

Our law firm is based in Rotterdam, a city of more than 170 nationalities, so we regularly have to ask the IJI for advice. For example, I had to deal with the recognition of a child by an Italian man, to which Italian law had to be applied. I don’t speak Italian so I could not do that myself. Nor did I have access to the sources which the IJI has.
