On 3 November 2001, we opened the door of Sol-4 Gestión for the very first time. This November, we turn 25. And like every story that truly starts from scratch, ours didn't begin with a grand plan or a big investment. It began with a project shared by two people, an office that had to be locked every time someone had to step out for an appointment, and the belief that you learn by doing.
Twenty-five years on, that way of working hasn't changed. We are still what we were from day one: your legal partner in Spain for buying, selling, inheriting and owning a property.
We started on our own, with the bare minimum
Mar and Vicente founded Sol-4 in 2001. Mar, then 27, took charge of the office in Benijófar, while Vicente was still working for another company.
Our first furniture was a gift from a kitchen company: they were kitchen units, and we adapted them ourselves to turn them into office furniture. We invested only what was essential, because we didn't yet know where the project would go, at a time when the Costa Blanca was seeing a strong wave of foreign buyers, mainly British and Dutch.
Our services didn't arrive all at once: we added them one by one, as our clients needed them. There was no manual. We learned along the way, side by side with each client.
A team that has grown with patience
Four years later, Vicente joined the day-to-day running of the firm. Then came Nieves. Over time, more people have come on board: some are still with us today, and others were part of the journey at their time. All of them mattered. Today we are a team of eight.
Our first office was a bare shell. Mar and Vicente designed the building work themselves, deciding as they went where everything should go. Years later we moved to much larger premises, also our own: our current office on Calle Aneto.
Businesses and the self-employed: growing alongside them
Not everything in these 25 years has been property sales and inheritances. From our early years, many local self-employed people and businesses trusted us with their accounts and taxes, and we have grown together: we have seen businesses start, weather crises and open new chapters. Today we remain by their side, with more and more clients who come from other countries to start a business here, and who value something that comes naturally to us: explaining their obligations in their own language, with the same closeness as always.
2012: the year our profession changed
In 2012, the Spanish Tax Agency began a change of direction that is still unfolding today. It brought the anti-fraud law, the new Form 720, which required residents to declare their assets abroad and hit our international clients directly, and the rise of VAT to 21%. Since then, every year has brought more controls and more obligations, also for the businesses and self-employed people we advise.
Being part of the Professional Association of Tax Advisers of the Valencian Community was real support through that period and helped us keep growing: through its technical backing, and because an association also stands by you. Today, Mar is the Association's delegate for the province of Alicante.
2025: joining forces to protect buyers and sellers
In 2025 we took another important step. Together with other lawyers from the Costa Blanca, we founded the Association of Lawyers Specialising in Property Law (AAEDI). It was born from a shared concern: the growth of unqualified advisers in our sector, people who handle property transactions without the necessary training or professional registration. Our aim is to protect consumers and to ensure that every transaction is in the hands of qualified professionals, because buying or selling a home is, for many families, the most important decision of their lives. Mar sits on its board as a founding member and secretary.
The way we work
If there is one thing our clients have told us again and again over the years, it is that they value the way we look after them. We believe a good adviser is not the one who solves problems, but the one who prevents them: that is why we take the time to explain, to anticipate and to review every transaction before taking a step, so that our clients can make decisions with full information and no surprises.
This way of working is not always the most comfortable. Sometimes our advice is not what a client wants to hear, and some prefer to take a different path. We respect that. And it is not unusual for them to come back to us, in time, precisely to solve the very issues we were trying to avoid. When that happens, we welcome them with the same willingness as ever, because our commitment is to people, not to being right.
We were also one of the first firms in the area to offer our clients their own private online area, where they can check their tax returns, their documents and the progress of their matters at any time, from any country. For people who divide their lives between two countries, having all their information at hand makes all the difference.
And all of this rests on values we never compromise on: honesty, confidentiality and a personal approach.
What hasn't changed in 25 years
Behind every step there is one idea: closeness, rigour and adapting to what each client needs, never taking anything for granted. We are with you from start to finish, just like on day one, but now with the experience of thousands of transactions behind us.
Mar and Vicente are the first to say it: these 25 years are not theirs alone. They belong to a team that joined along the way and, above all, to the clients who have trusted us year after year. Many of them since the very first day. Thank you.
What comes next
We keep growing, and we do it the way we started: by listening. Whether you are buying or selling a home, dealing with an inheritance, facing the tax side of owning property in Spain for the first time or keeping your business accounts in order, we will be by your side.
