For assets sitting in that country, often yes. Some legal systems reserve a fixed portion of an estate for particular family members, usually children and a surviving spouse, and those rules apply to the property regardless of what a will drafted elsewhere says. The will is not ignored, but it operates only on what is left after the reserved portion has been satisfied. This is a question of law rather than of tax, so it is answered with counsel in the country where the asset sits. What it changes on the tax side is who receives what, which is the input every estate filing depends on.

Rules in some legal systems reserving part of an estate for particular heirs, which can override a will drafted elsewhere.
Why it matters
Situs, not residence, drives most of this group. A holding's location decides which system reaches it, and the family usually discovers that when a custodian refuses to release the asset.

Where cross-border trouble starts
Domestic guidance is written for domestic facts, so it can be entirely correct and still unsafe to apply once a second country is involved. The check is whether the guidance contemplated a cross-border version of the same situation.
Where you will meet it
These pages are where Forced heirship stops being terminology and starts changing a number.
From term to filing
A term like this is worth ten minutes of reading and then a conversation. The reading tells you the question; the conversation answers it. Whatever you have is enough to start the conversation, including nothing but the dates.
One thing worth carrying away from any definition on this site: the term describes a category, and an authority assesses a file. Getting the category right is necessary and is not the same as having the file in order.

Files that look like this one
Governing law identified for each asset before a will was redrafted
A client with property in two countries and children from two marriages wanted one will to govern everything. We took the asset list and established, line by line, which legal system would decide who inherited each item, flagging the immovable property abroad as the line most likely to be governed locally whatever the will said. The engagement produced a written asset-by-asset note the client’s solicitor and local counsel both worked from, and a redrafted estate plan that stopped directing property the will would not in fact control.
Estate split between a reserved share and the residue under the will
Part of the estate was located in a system reserving a portion for children, and the will left everything to the surviving spouse. The executors had begun preparing filings on the basis of the will. We established what actually passed under local law, recalculated the spousal portion on that basis, and restated the reliefs that depended on property reaching the spouse. The engagement produced corrected filings, a documented allocation between the reserved shares and the residue, and a reconciliation the executors could give to each beneficiary explaining what they were receiving and why.
Filings rebuilt after local law redirected part of an inheritance
An estate had been filed on the will as drafted, and some time later local counsel confirmed that a reserved share had redirected part of a property to a child who was not a named beneficiary. Every downstream figure was affected, including the rental income reported since the death. We restated the ownership from the date of death, corrected the income allocation between the two recipients for each intervening year, and amended what could still be amended. The engagement produced a corrected set of filings in both countries and a written chronology explaining the change.
Overseas flat a custodian would not transfer on the will alone
The registry in the country where the flat sat refused to act on the foreign will and asked for documents evidencing the entitlement of each heir under local rules. The family read that as an obstruction rather than as the law applying. We set out what governed the property and what the registry was actually asking for, coordinated with local counsel on the evidence of entitlement, and worked out the tax consequences for each heir once the shares were known. The engagement produced a transfer the registry accepted and filings matching the ownership it recorded.
Beneficiary who received a reserved share and had to report it
A client learned they had inherited a fraction of a property abroad under rules they had never heard of, in a country they had no other connection with. Their question was what they now had to report. We established the cost base they were treated as taking on, the rental income arising from the date of death, and which of their existing filing obligations the new holding brought them into. The engagement produced a reporting position for the year of inheritance, and a standing schedule of what has to be disclosed each year while the interest is held.
Two wills reviewed for a family holding assets in two legal systems
The family had a will in each country, drafted years apart by advisers who had never spoken, and the two documents dealt with overlapping assets on inconsistent terms. We built a single asset schedule, identified the governing system for each line, and marked every asset that both wills purported to dispose of and every asset neither addressed. The engagement produced that schedule, a list of the conflicts for the two firms of solicitors to resolve, and a note of the tax consequences that would follow whichever way each conflict was settled.
A Retirement Plan That Grows Tax-Deferred in Only One Country
Cross-border retirement accounts are recognised by treaty, but the deferral usually has to be elected rather than assumed. The engagement checks whether the election was made, makes it where it was missed, and reports the account on whichever side requires it.

More on Forced heirship
It is the portion of an estate that a legal system sets aside for specified heirs and does not allow the deceased to direct elsewhere. The mechanism varies between systems: the fraction differs, the class of protected heirs differs, and so does whether it attaches to particular assets or to the value of the estate as a whole. The practical consequence is consistent. A beneficiary named in the will may receive less than the will promised, and a relative who is not named at all may receive something. Both outcomes change the tax reporting on the receiving side.
Start by establishing which law governs that property, because that determines who inherits it, and only then can anyone work out the tax consequences. Two things are worth doing before money moves. Get the position confirmed by counsel where the property sits, in writing, and get the actual distribution documented rather than assumed. Estates run into trouble when the tax filings are prepared from the will while the property in fact passed under local law to different people. The two versions then have to be reconciled, usually after an authority has already asked the question.
It changes who inherits, and that in turn changes the tax. Several reliefs depend on who actually receives the property rather than on who was intended to receive it: relief for transfers to a surviving spouse is the clearest example, because it follows the property to the spouse and does not follow an intention recorded in a will. Where a reserved share redirects part of an asset to children, the part treated as passing to the spouse shrinks, and any claim built on the will as drafted overstates the relief. So the legal answer has to be settled before the filing, not after it.
Not reliably, and the answer depends on where each asset sits rather than on where you live or where the will was signed. A will that validly excludes an adult child under the law of one country may be partly overridden as to property located in a country that reserves a share for children. Some systems allow a choice of governing law and some do not, which is a legal question for counsel in each country. From the tax side the point is narrower: plan the filings around what the law of each place will actually deliver, not around the instruction in the will.
As a general matter, immovable property tends to be governed by the law of the place it sits, while movable property such as bank accounts and shares is more often governed by the deceased’s domicile or habitual residence. That is a starting point rather than an answer, because the connecting factors and the exceptions differ by country and some systems allow an election. The working approach is to take the asset list, establish the governing system for each line, and get the uncertain ones confirmed locally. Doing that first is considerably cheaper than unwinding a distribution afterwards.
It starts with facts rather than structures: which countries have a claim on you, what each one taxes, and where the two overlap. From there the decisions are about order and timing — which country taxes first, where relief is claimed, and whether a filing or a certificate has to be in place before money moves rather than after. Most of the value is in the sequencing, because relief claimed late is usually relief recovered slowly. See international tax planning.
Generally the source country — where the income arises — taxes first, often by withholding before you receive it. Your country of residence then taxes the same income and credits what the source country took. That order is why timing matters: a residence-country return filed before the source-country tax is settled has nothing to credit yet. Getting the sequence right is most of the work. See international tax planning.
