Land Reform (Scotland) Act 2003
Everyone has the statutory rights established by this Part of this Act.
Those rights (in this Part of this Act called “access rights”) are—
the right to be, for any of the purposes set out in subsection (3) below, on land; and
the right to cross land.
The right set out in subsection (2)(a) above may be exercised only—
for recreational purposes;
for the purposes of carrying on a relevant educational activity; or
for the purposes of carrying on, commercially or for profit, an activity which the person exercising the right could carry on otherwise than commercially or for profit.
Access rights, reciprocal obligations and other rules and rights
The exercise of access rights does not of itself constitute trespass.
The extent of the duty of care owed by an occupier of land to another person present on the land is not, subject to section 22(4) below, affected by this Part of this Act or by its operation.
The existence or exercise of access rights does not diminish or displace any other rights (whether public or private) of entry, way, passage or access.
The existence or exercise of access rights does not diminish or displace any public rights under the guardianship of the Crown in relation to the foreshore.
The exercise of access rights does not of itself amount to the exercise or possession of any right for the purpose of any enactment or rule of law relating to the circumstances in which a right of way or servitude or right of public navigation may be constituted.
Access rights do not constitute a public right of passage for the purposes of the definition of “road” in section 151(1) (interpretation) of the Roads (Scotland) Act 1984 (c. 54).
A person exercising access rights is to be regarded as being in a public place for the purposes of section 53 (obstruction by pedestrians) of the Civic Government (Scotland) Act 1982 (c. 45).
Conduct excluded from access rights
The conduct which is within this section is—
being on or crossing land in breach of an interdict or other order of a court;
being on or crossing land for the purpose of doing anything which is an offence or a breach of an interdict or other order of a court;
hunting, shooting or fishing;
being on or crossing land while responsible for a dog or other animal which is not under proper control;
being on or crossing land for the purpose of taking away, for commercial purposes or for profit, anything in or on the land;
being on or crossing land in or with a motorised vehicle or vessel (other than a vehicle or vessel which has been constructed or adapted for use by a person who has a disability and which is being used by such a person);
being, for any of the purposes set out in section 1(3) above, on land which is a golf course.
Good luck with proving that the right to take a picture is the same as the right to sell it.
It goes without saying that different regions have different laws concerning access. But Adobe Stock Contributor Guidelines still apply.
